The Hendrickson TIREMAAX PRO-LB is a tire pressure control system that builds on the technology of TIREMAAX PRO, which has the ability to inflate, relieve, and equalize tire pressures across all wheel positions. TIREMAAX PRO-LB adds the ability to adjust tire pressure based on load. TIREMAAX PRO-LB helps eliminate the guesswork of tire pressure management. By monitoring the pressure in the air springs, the system reacts to changing loads automatically, with no input from the driver.
