Like Bread without Butter
A truck without Central Tyre Inflation is like bread without butter. Sure, you can eat it, but why???? Truth is, Central Tyre Inflation is an investment in future profitability.
Michelin says; “Tyres for commercial vehicles must be inflated to a pressure relevant to the load, speed and condition of use.” “Using the correct pressure is essential to the safe running of the tyre.” Note the “must”.
As the load changes, so must the tyre pressure. As the speed changes, so must the tyre pressure. As the conditions change, so must the tyre pressure….. This is “essential for the safe running of the tyre”.
But 99% of trucks run with only one tyre pressure, all of the time, wasting tyre life, extending braking distances, damaging roads, the truck, and the driver. The wrong tyre pressure increases tread wear and decreases the handling ability. Central Tyre Inflation puts you in control.
A small puncture usually ends up as a blow out, often wiping out two tyres, mudguards, and sometimes tail lights. Flying rubber could kill. Central Tyre Inflation automatically refills punctured tyres, and lets the driver know.
Everyone knows of the perils of under inflation. But over inflated tyres increase the risk of impact breaks, and increases tyre wear even more than under-inflation (Advantage).
Trucks that travel empty one direction, like tankers, tippers, and stock trucks, actually suffer much more tyre wear when empty than when laden, simply because their tyres are vastly over inflated.
Many Australian trucks travel extensively on gravel and dirt roads. Lowered tyre pressures here will significantly improve all operating parameters. Much better handling and ride, much better tyre life, much less tyre damage, longer suspension, brake, and drive train life, are all the amazing and real benefits. Any truck that operates regularly on gravel roads, and/or empty absolutely needs Central Tyre Inflation.
Here are some facts: Maximum legal loads for tandem drive tyres, in most states, is 16.5 tonnes. Correct tyre pressures for one typical Australian tyre choice at this load is 87 psi on highways. But, at a lower load of 10 tonnes, the correct pressure is only 50 psi. Many trucks use 100 psi. Fully laden, these tyres are 15% over inflated, wasting at least 10% of expected tyre life (Michelin)
On gravel roads, even lower pressures should be used. Pressures as low as 30 psi (at slower speeds) are used regularly, with great results. Traction increases up to 200%, tyre life increases by at least 30%, drive train loads are lowered, ride quality improvements of 10 fold have been measured, and the environment is better off too. Roads last longer, tyres and vehicles last longer. And drivers are in better health, with less stress and fatigue.
Central Tyre Inflation is the only practical tool that can adjust tyre pressures correctly. Using only one high pressure is as old fashioned as rag tyres. With costs steadily rising, and rates stagnant, operating smarter is the only choice. Ring AIR CTI for more information, on 03 51276 128 now.

Health & Safety Concerns All Transport
A vast percentage of truck drivers suffer from back troubles and stomach troubles. The financial costs affect everyone. The pain and suffering is much more personal. Most troubles are caused by poor ride characteristics and high levels of vibration.
Short wheelbase vehicles are the worst offenders. Tip trucks, and bob tail prime movers are often unbelievably rough, especially when empty. Kick, kick, kick all day long. Empty four wheel drive trucks are just as bad. The constant kicking from the super hard rear tyres hammers the back and neck for long periods, guaranteed to damage something over the years.
Most empty vehicles amplify every bump, corrugation, or stone creating a constant barrage of vibration, which is proven to damage the many vital internal organs.
Incorrect use of the first component of every suspension is to be blamed; the tyres. Tyre pressure is meant to be adjusted to suit the load, but who does. Typical tyre pressures when used on an empty truck can be 400% over inflated. We all know that a basket ball without air pressure won’t bounce, don’t we? Imagine a tyre 3 or 4 times the correct pressure. Every bump, every stone, every corrugation will be, and is, amplified at least 10 times, and can be up to 90 times worse than it should be. Every bump causes the back tyres to bounce, kicking the driver in the back, hundreds of times every kilometre. All because the tyre pressure is way excessive. Not only that, but the tyres, the suspension, and the truck are wearing out much faster too. Central Tyre Inflation makes tyre pressure adjustment easy, creating a much better riding truck, one that handles much better, and stops better too. A bouncing tyre has no traction. In fact, not only is the driver healthier, safer, and in better control, but the truck will be making more money.
What does an accident cost? Would shorter braking distances help? Would a better handling truck help? Of course. An over inflated tyre will have far less rubber gripping the ground. In fact, on many empty trucks, less than one third of the correct tyre contact patch is at work! That is when it is on the ground in between bouncing, that we all know about when we panic stop. The correct tyre pressures, especially on the drive tyres, will significantly shorten braking distances, and eliminate almost all jack knifes!!!!! Can we afford to run one high pressure any more?
Now that Central Tyre Inflation is affordable, there is no excuse for damaging drivers any more. In reality, Central Tyre Inflation is an investment, just like good tyres, and good trucks. Every tyre manufacture says the same thing; for instance, Michelin says “Tyres must be inflated to a pressure relevant to the load, speed, and condition of use.” From their latest tyre life chart, a 20% over inflated tyre causes a 21% loss in tyre life! How much does 200% cost you?
Tyre pressures must be optimized for each load, speed, and condition. No one can afford to throw money away like we have for the last 100 years. Costs are too high, lives too important, and profits too slim. Central Tyre Inflation should be on every truck. Ring AIR CTI for more information on 03 5127 6128..
Over inflated tyres, like those on almost every unloaded truck, can not conform to terra firma, can not stop or handle like it should, and will hammer the driver, the truck, and the roadway, to death.

False Economy
Tyres are boring, but money and safety is not. More money is wasted and lost on tyres than any other component. Same with safety. Incorrect tyre pressures wastes both money and safety. Thirteen percent under inflation wastes 10% of tyre life. Twenty percent over inflated also wastes 10% of tyre life too. Stopping distances increase with incorrect tyre pressures. Handling, ride, and control depends upon the correct tyre pressures. Incorrect tyre pressures cause most jack knifes and blow outs.
‘She’ll be right, mate” is the common thought as we thump our tyres. Talk about false economy! Even weekly pressure checks using a quality gauge, won’t protect you once you drive out the gate.
So how important is the correct tyre pressure? It’s everything. That bit of rubber wrapped around your wheels is useless without air pressure. The wrong pressure costs you money. Excessive tyre wear, poor traction, unnecessary suspension wear and tear, chassis and axle cracks, blown tyres, tyre damage, drive train wear and tear, poor ride and handling, accidents, and driver health and safety are just some of the costs.
So, what can you do about it?
Tyre pressure monitors, that constantly check the pressure and then radio this information to a dash mounted display unit is the absolute minimum that every vehicle should have. This is the law on all new cars in the USA. So it should be here. Who would be silly enough to drive without an oil pressure gauge or temperature gauges? Shouldn’t you know what is in that bit of rubber?
Tyre Pressure Maintenance systems are even better. These automatically add air pressure to any and all tyres, keeping them at the set pressures automatically, and then signalling the driver, if too much air is lost. Testimonials from around the world indicate savings of 30 to 50% of over all tyre costs. Who can afford to throw away 7 tyres on a twenty two wheeler? And yet most people do just that. False Economy.
Central Tyre Inflation (CTI) is the best. In fact, AIR CTI is the only means of adjusting your tyre pressures to the correct pressure all of the time. Other wise, you are wasting both money and safety.
And yes, almost all truck tyres are incorrectly inflated at least part of the time, if not all of the time. Talk about ‘false economy’.
And what is the correct tyre pressure? This is a good question. On the side of the tyre, it may say something like ‘maximum load 2650 kg at 8.0 bar 115psi. This doesn’t mean that 115 psi is the correct pressure for you. In fact, it is probably way too much for 99% of us. How many of us can carry 21 tonnes on our tandem drives? On a recent trip to Albany, we weighed an empty chip truck. The load on the drive tyres was only 8 tonne. His tyres were 250% over inflated! What’s that do to his tyre footprint? He’ll be driving around on 40% of the correct bit of rubber. The tyre will bounce off every bump making a pebble look like a gibber. If he puts on the brakes, it’ll lock up and slide, and tyre wear??? And he regularly travels off highways on rough dirt roads. What a hammering both the truck and the roads are getting. He’s making bull dust and wrecking his truck at the same time! Talk about false economy.
If money and safety are important to you, then do something about it. Modern technology will make your whole truck work better for less. Ring AIR CTI on 61 (0)3 5127 6128 for more information.

NEW TRADESMAN SERIES CTI
This system is designed to be super affordable. Without AIR CTI, any logging operation will be losing money. It is unaffordable to not have AIR CTI.
The Tradesman Series is a simpler system, basically comparable in features to our competitors. Suitable for tip trucks, service trucks, farm trucks, four wheel drives, and the likes, vehicles that do not work in the extreme, off camber areas that log trucks typically work. This system is ideal for older trucks, or beginners that are cash strapped too. We still believe that our Professional System is the right system for the professional logger, especially if drivers are used.
The Tradesman series uses a slightly simpler rotator, which is easier to machine, with high tech plastic parts, but still with the same carbon seals. These are excellent rotators, probably equivalent to our last series that has worked so well. The other beauty of these rotators is that different caps can be installed, to suit trucks, or trailers, or Landcruiser type vehicles.
The electronic controls are simpler, but still provide infinite pressure control. We’ve added a new feature that we call ‘auto set’. Upon start up, the system auto sets to a typical road pressure, like a pressure maintenance system, which is ideal for vehicles that are driven by several drivers. We’ve been testing this on our Suzuki Vitara for several months. This feature is great when my wife jumps in and drives to town. I don’t have to worry if she has checked and set the pressure. Plus, if she gets a puncture, it’ll be re filled automatically.
No isolator, and no quick connects, and less cost rotators. Other than that, the other components are basically identical with our Professional series. The Isolator is the main reason that the Professional system is potentially better suited when the vehicles are high and work off camber, i.e. on hills etc.
Retail prices for the Tradesman series is only AU$4,500 for a tandem drive system. Single drive truck, dual drive tyres only is AU$2,950. Four wheel drive trucks are AU$4,500 too. And, Landcruiser type 4x4’s run from AU$2,500 to AU$3,000 depending upon compressor requirements. Utes can be done for under AU$2,000. Think about how good a Falcon Out Back would be with it’s locker diff and AIR CTI. It would scare most 4x4’s in performance, and kill them in fuel economy and cost of running. Something like this would make good demo vehicles too.
Note: We have a range of 12 volt compressors from the proven VIAR 2.5 cu. ft. unit to the new Protector series that is supposed to pump 5 cfm! These retail for around AU$400 to AU$450.
Give us a call on 03 5127 6128 or 0427 110 203, and let us help you choose the right system for you.

We’re all fighting for our survival.
Neither our rates nor our selling prices have increased much in the last 20 years, but our costs have skyrocketed. Rates and prices are set by world wide competition, or so we are told. They are definitely out of our control (out of control, some would say). Governments could help by increasing their efficiency, which would lower almost all of our costs, via lower taxes. But, I wouldn’t hold my breath. So what can we do?
Our only choice, if we are to survive, is to lower costs. It’s the only business choice that we have. Correct tractor and plant selection is critical. Modern fuel efficient vehicles. Radial tyres for more traction. Super wide traction tyres are the right choice in many conditions. Correct sizing of implements provide better efficiencies. Minimizing compaction ensures maximum growth. With trucks, scales can help us carry the maximum legal load every trip. Automatic greasers ensure longevity, and minimal downtime. Air dryers minimize pneumatic problems. Alloy wheels allow more payloads.
Gone are ‘the good old days’ when we could plant a crop, or run sheep, and wait for the money to roll in. These days, we must be smarter, just to survive. Every tool, every vehicle, even ourselves, must be optimized to produce more for less. Tyres carry every load, pull every implement, converting horsepower to traction. Tyres should be optimized too, but almost no one does. This is a waste that we simply can’t afford.
To maximize traction while minimizing damage to our valuable land and crops, tyre pressures must be adjusted for every load and every terrain. Otherwise, you are wasting money. On hard ground, higher tyre pressures will increase traction, reduce rolling resistance, and improve tyre life. On soft ground, lower pressures provide substantially more traction, less wheel slip, lower rolling resistance, and improved tyre life. As tyre loads increase, like when using a front end loader, or carting an implement, or a load of wheat, tyre pressures must be increased. But, when empty, tyre pressures must be reduced, otherwise, punctures, stone bruises and tyre damage increase, tyre wear increases, and traction and handling reduce. Ride quality is another benefit from the correct tyre pressure, as is minimizing compaction. Tests have shown 2% more crop or growth because of less compaction from one pass, 7% less wheel slip, 6% less fuel usage, when ploughing. 90% improvement in ride quality is another advantage.
To maintain optimal tyre performance, hence optimal vehicle performance, and to minimize costs, tyre pressures should be adjusted and changed every time the load changes, and/or the terrain changes. If you don’t, it does cost you money. Tyre life, fuel economy, wear and tear, performance, and time, are all lost.
AIR Central Tyre Inflation makes on the fly tyre pressure adjustments easy. Simply rotate the dash mounted control to select the required tyre pressure. Simple, affordable, and very necessary. Ring them on 61 3 5127 6128. Australian made.

Without CTI, you’re only using 90% of your truck, or less.
Do you need more traction?
Do your tyres wear evenly?
Do you suffer from scalloped tyres, and cut tyres?
Do stones and rocks damage your casings?
Do rocks get caught between your duals?
Do your tyres last long enough?
Do rough roads cause you problems?
Does your truck ride well?
Do rough roads hammer out your suspension?
Do axle and or chassis cracks ever happen?
Do loose bolts, cracked fittings and brackets happen frequently?
Does your vehicle hop and skip across bumps?
Does your vehicle stop straight and quick on poor surfaces?
Do you worry about jack knifes?
Does your vehicle last long enough?
Do maintenance costs keep you poor?
Do you suffer from back or stomach trouble?
If any of these are important, then Central Tyre Inflation will benefit your business.
Are smoother roads better to travel on?
Does lowering the damage done to paddocks, tracks and country roads benefit you?
Does lowering the cost of building roads benefit you?
Does lowering the cost of maintaining roads benefit you?
Does lowering the dust and silt runoff into surrounding streams and creeks benefit your environment?
Does lowering noise levels improve your relations with your community?
Does lowering the compaction of the ground that we drive over benefit us?
Does lowering our impact on the environment benefit us?
We all know that by lowering the costs associated with the product that earns our income, that product will be more competitive, and there will be more money for all of us, and life will be easier.
Would you like to lower the overall long term cost of your truck?
Would you like to work more of the year?
Would you like to get stuck less, and need less tows?
Would you like to lower your maintenance, both in time and money?
Would you like to lower your trip times?

Facts on CTI and the Environment
By using the right tyre pressure for each terrain, load, and speed, there are significant environmental benefits. Correct pressures and CTI reduce tyre use significantly, reducing both the environmental impact from their manufacture, and the problem with disposal. Softer tyres reduce impact loads on trucks and trailers, reducing vehicle wear, damage, and repairs. By increasing the life of the vehicles, we are reducing the environmental impact of each vehicle, from the mining of the raw material to the power required in manufacturing. Lower tyre pressures reduce the need and cost of roads. The added traction means steeper grades can be used, lessening the length of many roads. The reduced road damage means less gravel and rock is needed to stand up to the job. The reduced road damage and the self healing ability of low pressure tyres mean less road maintenance is required. And, by spreading the load over a larger area, much less silt and dust is created, improving the life of our streams, rivers, and catchment zones. Plants near the roads also benefit, as do humans who live close by. The benefits are significant:
*Reduced road maintenance by up to 80% NATC
*Dramatic reductions in sediment from road surfaces with lower pressures

Facts on CTI and Road Savings
Road and track costs are a major part of any timber harvesting process. Any means of reducing this cost has to benefit the entire industry. Central Tyre Inflation has been around for 60 plus years, providing added vehicle mobility, while improving handling and safety. Many government and industry tests have also proven substantial savings in road design, building and maintenance. For instance, the added traction means steeper grades can be used. The reduction in road damage mean less track preparation and less rock and gravel need to be carted. Less wheel spin and softer tyres mean less grading and maintenance. This adds up to substantial road and track savings:

Fact on CTI and Agriculture
Tyre pressures on tractors are always a compromise. Higher pressures are required for transport needs or load carrying, like front end loaders, or carrying round bales. But lower pressures are far better where traction is needed, and lower compaction is important. Central Tyre Inflation is used on farms in Europe already, with many in the USA trying it too. As our farming community realize the damage that compaction does to their income producing ground, and the amount wasted on fuel and tyre slip, CTI will become more important. Farmers will insist that contractors use intelligent and kind pressures when working their land. And, contractors and big farmers will realize that they can’t afford the waste of not using AIR to their advantage. Proven by:
*Average ride improvement of 99%, ranged from 18 to 22% improved. USDA Agric. Research
*CTIS would improve the health and alertness of operators, and extend the time that they could effectively and safely operate the vehicle, USDA Agric. Research

AIR CTI Central Tyre Inflation is well engineered, affordable, and easy to use. The many advantages outweigh any disadvantages by 10 to 1. Contractors need to control their costs, and constantly improve their services to remain competitive. CTI reduces costs, improves mobility, reduces trip times and job times, and improves the job performed, while reducing any negative paddock damage. Many benefits are cumulative. For instance, it takes more energy to plow a compacted soil. And, CTI provides more tractive power with less wheel slip. Hence, less energy is required (plows follow your tyre that is compacting the soil), and you have more traction, with less wheel slip. You win twice. Think about it.

*Waiting to be pulled out costs time, and reduces the number of trips.
*Blow outs and lost tyre treads wipe out mud guards, lights, etc.
*Better handling, makes the vehicle safer.
*Trucks cost money all of the time, specially when they aren’t working.
AIR CTI has hundreds of customers, and the feed back from them reinforces all of the above. Our own experience with all of the above proves to me that any truck operating off highways is losing money by not having and using Central Tyre Inflation. Almost every weekend, we are out testing CTI in the real world. Traction gains let us go places, often in two wheel drive, where other’s need four wheel drive in two wheel drive. And ride quality is just so much better. Once you have CTI, you’ll never have a vehicle without it.
And, of course, AIR CTI is the best CTI at an affordable price.

The 2006 Mountain Cattlemen Protest Drive
Back in 1988 the Wonnangatta Station property was purchased by the Victorian government with plans to lock up this area for ‘posterity’. This became the Alpine National Park. Now, instead of this area earning Victorian taxpayers an income, whilst being successfully managed for some 150 plus years, Victorian taxpayers now pay a small fortune every year, with the net result of thousands of acres of blackberries, thistles, St. John’s Wart, and other noxious weeds covering this beautiful land.
One hundred and seventy years of mountain cattlemen traditions are being lost on top of the destruction of this once beautiful and productive station. A protest rally has just been accomplished, driving a couple of dozen cattle from Dargo, from Mansfield, and Heyfield areas to bring attention to every Australian, the catastrophic results of DSE and Parks land care policies. This protest included such luminaries as Doug Treasure, the Mountain Cattlemen’s Association president, Charlie Lovick, a very well known high plains cattleman, and Graeme Stoney, another cattleman and esteemed member of the Victorian Upper House. Doug’s sisters, sons, nieces, and family, along with numerous Lovicks, plus many more supporters helped make up over 100 cattlemen and women, essentially breaking the law, to bring this disaster to the public attention. The state of this park is a total disgrace, plus the 15 to 30 times extreme fire danger from the uncontrolled undergrowth means this area could easily be the catalyst to another black Friday.
When the Parks people were asked why they were harassing this group, instead of doing something about the terrible weed problem, or fuel reduction, their answer was simply ’no comment’ When the Parks vehicle got bogged on the terrible tracks, and Stoney’s vehicle pulled them out, they still continued pursuit of our cattle. When asked why they had not interviewed us when we were all together, and waited until the TV cameras had left, they again said ’no comment’. And then they wondered why we stated ’no comment’ when they asked us who owned the cattle. Again I ask them, why did they have at least three vehicles, including the police, checking our protest group out, when the real damage has been done by their departments and respective governments. Who are the criminals here?

Our honest, taxpaying, cattlemen and cattle women continued our protest drive on to the huge Mountain Cattlemen's’ Get Together at Rose Creek, successfully completing a very satisfying heritage trip. Not being a cattleman myself, but believing that all Australians should benefit from our vast beautiful continent, I was very impressed with the way these fine Australians conducted themselves. The horsemanship, the ease of cattle control, the care for others, and the sympathy with the environment are all the traits that have made this country the best place in the world to live. I was proud to be with them and support our true Australian heritage.
Our greatest invention, is ignored, misused, abused, and wasted!
The single invention that made wheels really useful, that John Dunlop invented, is without a doubt the most abused, most ignored, the most misused, and most misunderstood invention, ever. Back in the 1888, John Dunlop put air inside a flexible donut, and made a fortune. The first use was on bicycles! The simple act of encasing pressurized air inside what we call a tyre, made every modern vehicle possible. We simply could not survive without the ‘pneumatic tyre’.Air pressure supports every vehicle. The tyre doesn’t. Take the air out of it, and you have a worthless piece of rubber, steel, and various cords. The air is the secret. And almost every one of you reading this doesn’t use that air affectively.
Racing car drivers do. They know that if they ignore air pressure, they will lose. And so do almost all of you. If you don’t optimize your tyre’s air pressure, you are losing. You’re losing tyre life, tyre traction, braking ability, cornering ability, and you’re destroying your tyres prematurely. And, last time I checked, tyres cost lots of money. Ignore your tyre pressure, and you are losing lot’s of dollars.
But, tyre value is not all you lose. If you can’t stop because your tyres are bouncing, or because only a small portion of your tyre is trying to grip, how much does that accident cost, and your insurance premiums? If your tyres are beating your suspension to death, bouncing off every rock, every bump, every pot hole, how much damage is being done to your suspension bushes, to your shock absorbers, to your springs, to your truck’s chassis, to your truck, and to you, the driver?
A speedway sprint car driver will run a different pressure in each tyre; his left rear may be 3.5 psi. If the track is a bit slow, he may lower his pressure a quarter of a pound. A Bathurst V8 Holden will adjust his tyre pressures up, or down one pound, just to be competitive. A rally driver will change his pressures to suit the road. And you can too, with affordable AIR CTI. Just think, in 2004, the top 10 places in every class of the Paris to Dakar rally had CTI. Last year, they stopped CTI because ‘It was too expensive”. But, AIR CTI isn’t. In fact, you can’t afford to not use AIR CTI.
So, why is tyre air pressure so important? Tyre design is a compromise. The contact patch, the bit of rubber that actually touches the ground, is the Holy Grail. Every tyre engineer’s
Ambition is to have a nice even contact patch, the full width of the tyre, and spread fore and aft in a nice circular or oval shape. Too much air pressure and the edges of the tyre lift off the road. Then, only the center bit of the tyre is touching, and you lose traction, lose tyre life, and suffer from a number of other nasties. Too little air and the contact patch lengthens, the load on the edges increases, deflection increases, and, at speed, this flexing creates heat, which will damage the tyre. Another down side, is the lateral stability is less, the vehicle wallows, floats, doesn’t steer as well, like, well, like driving on a flat tyre. The air pressure must be balanced by the load. And the load must be balanced by the tyre’s air pressure. So, every time you change the load, you must change the tyre pressure, or you are wasting money.
But on gravel roads, or worse, a tyre’s requirements change. If you run correct road pressures, your tyres will be too hard. Extra tyre deformation is needed to absorb the road irregularities, like rocks, and bumps. A too hard tyre will ride on top of every stone, slipping and sliding, like on marbles. If the tyre can conform around the stones, and grab the roadway, traction will significantly improve. Softer tyres, ones with less air pressure, also handle better, as the extra flexibility lets the tyre grip better, hence the ridiculously low tyre pressures that speedway cars use. The extra flexibility also adds suspension articulation, a feature sadly missing on almost all modern trucks. This extra articulation, combined with the extra flexibility provides an amazing amount of extra traction. A standard tandem drive truck, a 6 x 4, with CTI will outperform a 6 x 6 truck, with considerably lower running costs, and significantly lower tare weights. With CTI, a B double will pull out and pass a stuck conventional with only one trailer. Pressures down to 30 psi can double traction on some surfaces. It’s quite awesome.
Added available traction, with tyres on the track, significantly reduces tyre slip, which reduces tyre cuts, wear, uneven wear, punctures, stone damage, pig rooting, axle hop, and the extreme loads they place on your drive train. By absorbing bumps and rocks, and not bouncing off them, impact loads on the suspension and chassis is reduced significantly, actually measured as 1/10th! Hence significantly reduction in suspension and chassis maintenance, cracks, and breakages.
Balancing tyre pressure to the job also reduces our environmental impact. Roads last longer, gravel roads and tracks don’t break up so soon. Pot holes, corrugations, ruts, dust, all are reduced when the correct tyre pressures are used. Corrugations are caused by high pressure tyres, and are actually ironed out by low pressure tyres. Better traction, better ride and handling, combined with better roads, lower your costs, and improve your trip times.
Use of the correct tyre pressure will significantly reduce our impact on the environment. Less rutting, and less road damage reduce the cost of our roads. Less tyre use and longer truck life add up to less cost. This means less waste and damage to our environment. Less silt runoff and less dust reduces our impact on our streams and rivers. CTI benefits our environment.
AIR CTI’s benefits are proven in numerous scientific tests throughout the world, and in real life. AIR CTI is an investment in your future that simply improves every aspect of your operation. You can not afford to not have CTI.

CTI is Variable Tyre Pressure?
CTI is the common abbreviation for Central Tyre Inflation, but, what is it? CTI really should be called Variable Tyre Pressure Systems, because that is what it does.So, what is Variable Tyre Pressure, and why?
Imagine your motor only had one throttle setting, flat out, or nothing. Many WW1 aircraft had no throttle. It was either full power, or ‘killed’. We’ve learned a few things since then. A variable throttle works much better.
Imagine only one gear in your gear box? Henry Ford produced 15,000,000 Model T’s that had only two gears. Modern cars have 4, 5, or 6 speed gear boxes. Many trucks have 18. It works better.
Think about it. You choose the speed your wipers wipe, your heater blows, the volume of your radio, how hard you brake, because it works better.
Variable Tyre Pressure works better too. If you could change your tyre pressure when the load changes, or when the road surface changes, while driving, everything works better. Tyre pressure charts are available from every tyre manufacturer specifying the correct tyre pressure for every load and speed. They know that tyre pressures should be changed when ever the load or speed changes. There is no single correct pressure. The traditional tyre pressure is almost always excessive, costing you money in lost traction, lost tyre life, lost suspension life, lost vehicle life, lost time, lost comfort, and loss of life. The correct tyre pressure will work better in every aspect.
CTI, or Variable Tyre Pressure Systems isn’t new. Every army uses CTI to enhance mobility, and save lives. The 1942 Army Dukw had CTI. It worked better. The majority of log trucks in Australia, New Zealand, Canada, South America, and Europe use CTI. It makes their job better.
So, why isn’t everyone doing it? Perceived cost is the main reason. But, even when CTI cost as much as $26,000 (other’s systems cost) for some prime movers, in reality, CTI doesn’t cost anything. It makes you money, it saves you money, and it saves the environment.
Through radical new designs using innovative ideas and modern materials, dedicated in house manufacturing, and eliminating the ‘cream’ that was rife before AIR CTI, AIR Central Tyre Inflation is now affordable. In fact, most working vehicles can not afford to not have AIR CTI. It is an investment where everyone wins.
Trucks get more tyre life, even tread wear, less tyre damage and punctures, longer case life, more traction, better handling, quicker stops, softer ride, less vibration, longer suspension life, longer truck life, reduced maintenance, and better resale value. Up to double the traction means less bogs, and more working days. Less track and paddock ruts and damage means more working days. The extra traction means 4 x 4’s, 6 x 6’s, duals, or super wide tyres usually aren't necessary. And if they are necessary, AIR CTI is a must. This again saves money, reduces operating costs, and improves your payload.
AIR CTI doesn’t cost, it makes and saves money. AIR CTI is the most cost effective improvement that you can purchase, and it’s affordable. In fact, most working vehicles are losing money without AIR CTI. Anyone going outback, working on the land, or working in hostile environment should have CTI. The worse the conditions, the more you need AIR CTI. Tyre damage and premature wear, you need AIR CTI. Traction problems, track damage, environment concerns, you need AIR CTI. From road trains to Landcruisers, from service trucks to road graders, from broad acre tractors to market gardeners, to hobby farmers, CTI simply works better.
AIR CTI, the only Australian manufacturer, has systems for every vehicle type or use. Proven in the harsh Logging Industry Australia wide, in the Fertilizer industry, on four wheel drives every weekend, AIR CTI is the most affordable, and best system available, full stop.

Too Much Food Hurts You - Too Much Air Pressure Hurts You Too
The correct amount of food makes us work at our optimal level. If we eat too much, we feel bloated, we slow down, our bodies suffer, our work suffers, and our longevity suffers. It’s the same with tyres. The correct amount of air pressure is mandatory. Too much air, and traction decreases, tyre life decreases, bumps are amplified causing unnecessary suspension and vehicle wear and tear, and damages the driver. With too much air, wheel slip increases, axle tramp and tyre bounce increases, and fuel is wasted. And over 90% of you will have too much air in your tyres. It doesn’t matter whether you’re in a car, a truck, or a tractor, too much air will cost you heaps.
Poor handling and poor braking can end in a life threatening disaster. Poor handling increases driver workload and stress. Rough riding has been proven to damage humans. Poor ride also slows down the job. Excess wheel slip wastes fuel, wastes rubber, and slows down the job. Not only is rubber ripped off, but tyre damage is 3 times higher. Staking, major tyre damage and blow outs are more symptoms of incorrect tyre pressure. So, what is your tyre pressures?
What, in fact, is the correct tyre pressure? No, it’s not the pressure written on the tyre, nor is it the pressure in the owner’s book. Not unless you operate your vehicle at the maximum weight at the maximum legal speed on highways, at all times. The correct tyre pressure must be matched to the actual tyre load. Change the load, change the pressure, or it will be incorrect, and cost you money. Change the surface, change the pressure. Change the use, change the pressure. Or it does cost you money.

Contractors, big farmers, high use tractors, log trucks, service trucks, low loaders, farm trucks, incorrect use of your tyres is costing you big dollars. If you travel between farms, drive tractors on roads, change implements, or if your truck regularly travels on gravel roads or worse, if wheel slip is a problem, your tyres don’t last long enough, or you need extra traction, Central Tyre Inflation (CTI) will make, and will save you money.
Vary Your Tyre Pressure - To Suit the Conditions - It Works Better…
Australian manufacturer, AIR CTI makes the best Central Tyre Inflation System (CTI) available, at the best price. But what is CTI, and why should you have it?
Conventional tyre pressures that we have all used is, in reality, the correct pressure for one, and I mean only one condition. That condition is for a fully loaded vehicle, operating on paved roads, at high speed. On any gravel road, track, city street, or when driving alone, this pressure is too high. And, on wet, rainy days, a higher pressure will be better. The correct tyre pressure depends on the weight of the vehicle, the speed traveled, the road type, the soil type if off road, and the job at hand. If you change the tyre size, pressure requirements also change.
For instance, the AIR CTI test vehicle, a Suzuki Vitara, with standard tyres, is specified for 28 psi. “With slightly larger tyres, we use 22 psi on the highway when empty, 28 to 34 if it rains, or on windy roads. On gravel roads, we drop pressures to 12 to 15 psi, depending upon the surface, and on difficult tracks, or sand, we go down to 6 psi.” says Chet Cline, the owner of AIR CTI. “Twelve psi on our gravel tracks around Walhalla makes the little Suzi handle like a rally car. It’s unbelievable.” he says. “Traction on tough, rocky tracks is just amazing at 6 psi.”
On our F350 4x4 tray, with 33 inch tyres, we use 32 psi in the front, and only 18 to 20 psi in the rear when operating on highways, when empty. We recently supported the High Plains Cattlemen protest through Wonnangatta, carrying 800 kilos of portable cattle yards. We used 45 psi in the rear tyres on the highway, and 18 psi throughout the Wonnangatta. Performance was awesome.
A Hi Lux with a full load may need 60 psi in the back tyres. Take the load off, and the tyre pressure should be drastically reduced. If not, it’ll ride like a truck. And tyre wear will be poor, braking will be poor. Handling, especially on bumpy corners may be disastrous.
AIR CTI makes systems for any vehicle, from Log Trucks and Road Trains to Tractors and Fertilizer Spreaders, to standard 4 x 4’s. Check out their web site at www.aircti.com, or ring Chet at 03 5127 6128. Australian made, and proud of it.
