The OEMTOOLS Tire Transport Dolly with Extensions, No. 24865, is designed for efficient, one-person transport of car, light truck and SUV tires and wheels. The dolly is outfitted with two swivel casters that allow users to maneuver tires and wheel assemblies throughout the garage. Simply lock the two locking casters when servicing a vehicle so the dolly stays in place while stacking up to eight tires or five wheel assemblies. Four sturdy height extensions raise the working height to allow a more ergonomic posture while working with heavy tires.
