This is grossly over inflated,

wasting 40 to 60% of the

tread life

240 x 184 mm is the correct footprint for highway use. (11R22.5) This pro-vides the best combination of trac-tion, tyre life, and comfort.

An empty truck with typical pressures have a much smaller footprint, which increases stopping distances, wastes rubber, damages the casing, and hammers the truck to death.

Note: 33mm vertical deflection

This tiny footprint is only the size of a man’s palm

Note: No flat contact patch No vertical deflection

AIR CTI SHOULD BE

Semi Trailers need to stop straight and true. If the drive tyres don’t grip, jack knifes happen. Steer tyres always have good grip. They always

have a similar load, and tyre footprint. The trailer tyres are always over inflated, and

suffer loss of grip, which then pushes the drive tyres sideways, which is not good.

Dog Trailers can be worse, because there is even less weight on the drive tyres. We’ve

seen 4.5 tonne trying to control 16 tonne! Talk about the tail wagging the dog!

Yes, ABS will stop this loss of control.

But, a dog with all of it’s feet on the ground will

stop much quicker! AIR CTI IS SAFER.

Hard tyres bounce off bumps, hammering your truck and driver. The impact loads are immense,

Damaging springs, axles, suspension, etc.

Soft tyres absorb bumps, and are your first air suspension. Impact loads are tiny in comparison,

doubling the life of most of your truck.

Dragging Heavy Trailers up and down hills

with tiny patches of rubber simply rips tyres to death!

ON EVERY TRUCK

Will the driver know before it blows? Will the other tyre blow in sympathy?

AIR CTI eliminates most Blow Outs and

Roadside Tyre Changes.

A 5 psi difference in pressure causes a 7 mm difference in rolling distance. The

smaller tyre will be dragged

a 1/4 kilometer every 100 k’s!

Lower Pressures Reduce Drive Train Loads. Tests Showed a 30% Minimum Reduction! Less Load = Less Stress = Longer Life

Blow outs and Road

side tyre changes

are dangerous.
