Does Tyre Pressure Affect Tyre Performance?

Does Tyre Pressure Affect Tyre Performance?

Tyre pressures are a tool that our industry ignores.   Transport wastes a lot of money, a lot of time, and a lot of lives.   Truck driving is now recognized as the most dangerous industry, even when our researchers didn't even look at Whole Body Vibration (WBV) which is a known problem in the northern hemisphere.   Truck drivers have the shortest life expectancy of any industry.   And, now, with our new Regulations and COR liabilities, we must do everything 'reasonably practical.'   Tyre pressures in heavy trucks have been ignored for a hundred years, even though the tyre manufacturers have been printing Load to Inflation tables for decades.   Several government departments from many countries have researched this issue, with numerous technical reports; yet, our industry continues to ignore these recommendations and scientific knowledge.

COR requirements mean that you, and everyone else in our industry, must take ownership of this issue.   We can not continue running under inflated steer tyres, and severely over inflated drive and trailer tyres.   This belief that 100 psi, or 110 psi is ideal for every truck tyre is wrong.   The cost is huge.   The ramifications when the legal industry and the media recognize this problem will be equally huge.   We must act now.   We must educate and we must do what the tyre manufacturers recommend.

 
Once upon a time, tyres did not exist. Things rolled on round logs or stones. The wheel was invented. They soon discovered the wheel needed protection, some sort of ’tyre’ to protect the wheel from wear, and to provide traction.
Some dude by the name of Dunlop invented the pneumatic tyre, originally for push bikes. Pneumatic tyres developed and improved. Michelin made a huge improvement when they developed radial tyres. Modern tyres are marvels of engineering, providing traction, cushioning the load, and a long service life.
Of course, man being man, we started racing them. We race every variety from push bikes to heavy trucks. Racing teaches lessons fast with deadly results if we get it wrong.
Tyre pressure is a tool that all racers use. Tyre pressure sets the tyre footprint size. There is one perfect tyre footprint for every load and use. Change the footprint size, and you lose.

But, our trucks use one pressure for all tyres, regardless of the load on each tyre. Why would anyone run the same pressure on a tyre supporting 3 tonnes and on the same size tyre carrying only 1.7 tonne. Why would anyone run the same pressure on the same tyre when it is supporting half a tonne, or less, as on an empty truck?
Transport totally ignores the tyre manufacturer’s recommendations.
This is simply dumb, and dangerous.

AIR CTI has been manufacturing Central Tyre Inflation in Moe, in Victoria, for 20 years. AIR CTI is very practical, very reliable, and is proven to stand up to Australian conditions. Over 10,000 trucks use AIR CTI, from Bee Keepers to out back Road Trains. We halved the cost and tripled the guarantee. AIR CTI manufactures both driver controlled and fully automatic systems that automat-ically set and maintain the optimum tyre pressures. Driver displays ensures he knows his tyre condition at all times. Blow outs are virtually eliminated. Tyre life increases by at least 30%. The truck rides and handles better. Drivers are more comfortable and suffer less fatigue. Our world is a better place.

The facts on the many benefits of Optimum tyre pressures is indisputable. All reports and num-bers quoted are documented and in AIR CTI files.


The improvement to truck safety is indisputable.


The fact that AIR CTI pays for itself in just tyre savings makes it a necessity, not just ’reasonably practical.’

CTI must be made mandatory on all PBS trucks. Optimum tyre pressure training must be started immediately. The Chain of Responsibility makes this a necessity.
Central Tyre Inflation must be our future.
