Advanced Automatic Tyre Pressure Control System

TIREMAAX PRO  Tyre Pressure Control System

TIREMAAX™ PRO, an advanced automatic tyre pressure control system for the trailer industry that is capable of actively inflating or relieving the tyres to a pre-set pressure level. Its straightforward mechanical design balances tyre pressure at every wheel position by continuously monitoring and adjusting tyre pressure through the inflation or relief of the tyres based on changing environmental conditions – an important feature for achieving maximum tread life in any tyre configuration.

TIREMAAX PRO helps fleets and owner operators in their efforts to minimise costly tyre wear and improve productivity and fuel mileage. It provides a simple, responsive approach to help you extend tyre life and increase fuel efficiency. This patented system draws from the vehicle air supply to maintain your trailer tyres at the optimum pressure.
