The Martins Industries Pneumatic TBR and OTR Tire Spreader, No. MTRS-HD, is ideal for truck, bus, and commercial/public utility tires with its heavy-duty, automatic tire-lifting platform and spreader hooks, tire rollers, and roll-on ramp. Swivel hooks on both sides sit on the bead without damaging it and adjust to tire width and sidewall height. When ready, use the first joystick to lift/lower the tire and the other one to spread/release it. The tire spreader features a large tool tray as well as an air outlet on the base. It also has a wide-opening lamp mounted on the fully flexible arm to allow users to illuminate and inspect the inside of the tire.
