The Coats Maxx 80 Rim Clamp Tire Changer (Model 800MAXX80A) is the air-driven configuration of Coats' most popular professional tire changing machine, purpose-built for high-volume automotive and light/medium truck service shops that operate on shop air rather than a dedicated 220V electrical circuit. Powered by an air motor delivering up to 4HP at 110-175 psi, it handles alloy and steel wheels ranging from 6" to 24" in rim diameter, up to 16" wide, with a maximum tire diameter of 50". The Maxx 80 comes fully equipped with the patented Robo-Arm bead depressor, RoboRoller, Grip Max 2.0 protective clamps, and a premium storage cabinet, making it one of the most comprehensive standard accessory packages in its class. Built and backed by Coats (Hennessy Industries), it is engineered for demanding shop environments where speed, versatility, and wheel protection are critical.
