TRT Truck and Trailer Parts
TRT manufacture and install Traction Air®, Australasia's leading central tyre inflation system (CTI). Traction Air CTI has been designed with features to make your on and off-highway vehicle operations safer and more efficient.
Traction Air® offers a number of pressure management systems to the market:
Traction Air® CTI – G Series
Traction Air® CTI – E Series
Traction Air® Tyre Pressure Control for Cranes
Traction Air® G Series is used throughout New Zealand and Australia to more remote countries like Papua New Guinea and Laos.
Traction Air® E Series is the latest advancement is CTI technology from TRT. This new system is available in all locations but is specifically designed for the harsh operating environments of Scandinavia, United Kingdom and Europe. So our Australasian customers will gain these benefits too.
The expert CTI team at TRT, or one of its agents, installs systems in all locations throughout Australia, New Zealand and the Asia Pacific region.
On and off-highway vehicle operations that regularly use Traction Air® CTI includes forestry haulage, construction and equipment transport, agriculture, tractors, stock trucks and spreading, tanker operations, access equipment, construction and infrastructure and much more. Ideal for both tractor / prime mover and trailer units, tyre pressure management has never been easier.
TRT’s focus on continuous improvement, technology advancements and integration of industry requirements is a key to meeting the changing demands and conditions of transport businesses. This has lead TRT to develop both the G Series and the new E Series that are loaded with features and functions to help your operation every day.
Traction Air® Tyre Pressure Control
TRT has further developed the new E Series Traction Air to manage tyre pressure control. This is an ideal solution for cranes that have variable PSI depending on operating and ground temperature, load size, operating surfaces and more.
Normally, managing the tyre pressure is a manual process for operators when setting up a crane for the start of the day or changing conditions during the day.
Traction Air’s tyre pressure control options allow for automatic management from the cab of the crane, operator to monitor in realtime and the system to automatically inflate or deflate to maintain a constant PSI. This saves the crane operator precious time in their workday. This is available exclusively on TRT’s new TIDD PC28
3 year / 500,000 km Warranty
We stand behind what we do. Traction Air® is backed by more than 22 years of innovation and a 3 year / 500,000km warranty on all electronics and pneumatic valves and a 12-month warranty on hardware including wheel ends and plumbing on both the existing G Series and the new E Series.
The focus on continuous improvement and industry feedback is a key to meeting the changing demands and conditions of transport businesses. This makes the CTI system, loaded with features and functions that will help your operation every day.
"They have listened to us as a client when we have requested product improvements and they have stood by those improvements."

Why do you need a Central Tyre Inflation System?
Improved Operator Safety
Moving from a surface that needs the reduced PSI to a sealed road or highway can cause tyre damage. If a driver misses changing the tyre pressure it will cause significant tyre wear. If low PSI results in a tyre blowout, it could result in a more serious accident and involve other road users. This risk is mitigated with Traction Air® as the tyre pressure automatically adjusts through an integrated GPS receiver to ground speed – a key safety feature that also saves cost through better management of tyre wear.
The correct pressure setting for an 11R 22.5 tyre at 100kph is when the sidewall is deflected by 12% of its unloaded height. At 10kph, that sidewall deflection can be increased to 30%, which will double the tyre footprint and halve ground pressure. If you are able to maintain the correct tyre sidewall deflection ratios, you will get huge traction advantages including reduced wheel slip and reduced vibration. By managing the vibration you will be able to achieve the greatest cost savings while helping to reduce overall operator fatigue. The Traction Air® automated tyre pressure monitoring system can drive these efficiencies across your fleet.
