Traction Air® is TRT’s advanced Central Tyre Inflation (CTI) system, designed to optimise tyre pressure in real time, improving traction, reducing wear, and keeping your fleet moving across any terrain.
Smarter Pressure. Total Traction.
The development of Traction Air® began in 1997, with TRT focused on improving vehicle performance across changing conditions. That innovation has evolved into today’s Traction Air CTI system, now proven across thousands of vehicles throughout New Zealand and Australia.
The challenge
Operating across sealed roads, gravel, mud, and soft ground creates constant changes in traction and tyre performance. Fixed tyre pressures force a compromise, reducing grip in off-road conditions and increasing tyre wear, fuel consumption, and instability on-road.
This limits efficiency, accelerates tyre degradation, and can impact safety across varying operating environments.
The Solution
Central Tyre Inflation, controlled from the cab. TRT’s Traction Air CTI system enables operators to adjust tyre pressure in real time to suit changing conditions.
By optimising tyre contact with the ground, it improves traction, reduces tyre wear, enhances safety, and increases overall vehicle efficiency on any surface.
-
Optimised Traction
Adjust tyre pressure to suit changing conditions, improving grip across sealed roads, gravel, mud, and soft ground.
