TRT's own Central Tyre Inflation system, manufactured and supported across New Zealand and Australia since 1997. Semi-automated tyre pressure control from the cab, with parts, dealer, and service exchange support available across both countries.
Smarter Pressure. Safer Roads. Lower Costs.
CTI systems built to keep your fleet moving
Traction Air® was developed by TRT in 1997 to solve a real problem: logging trucks in New Zealand needed a smarter way to manage tyre pressure across haul roads without stopping.
Since then, the system has been fitted to more than 4,000 vehicles across New Zealand and Australia, evolved through three generations of design, and is now backed by a 3 year / 500,000 km warranty on all electronics and pneumatic valves.
Parts, service, and dealer support are available throughout both countries.
Central tyre inflation suits any operation that moves between sealed roads and unsealed terrain in the same shift.
Forestry haulage, civil construction, agriculture, tanker operations, stock trucks, access equipment, and spreading rigs all run CTI systems across New Zealand and Australia.
If your vehicles are managing variable surfaces and loads daily, the system pays for itself in tyre life, fuel, and traction alone.
