Tire Pressure Control System

TIREMAAX PRO Tire Pressure Control System

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