The Coats 90C Center Clamp Tire Changer features a center locking-clamp design that is easy to use, fast, and helps prevent metal-to-metal contact with customer wheels. It also comes standard with a leverless duckhead mount/demount tool and auxiliary bead sealer. The leverless duckhead acts as a traditional helper device and eliminates traditional tire tools that can mar the surface due to application difficulty, the company says. The Coats Auxiliary Bead Sealer (ABS) is designed to tap into the tire changers surge tank, providing additional bead seating volume. The ABS also assists with sealing difficult applications. The 90C is capable of servicing tire rims from 10" to 30" in diameter.
