Abstract
Abstract Tire servicing apparatus including a tire gripping tool base adapted to be mounted on a vehicle, a crane boom or the like. The base movably mounts a pair of opposed tire gripping members which may be moved towards and away from each other to grip or release a tire for servicing purposes. Hydraulic cylinders are provided for moving the tire gripping members relative to the base and an elongated flexible strap is operatively connected to both of the tire gripping members and has a length sufficient to define a loop of a size to be circumferentially received about a tire. When the loop is so disposed, the motors may be operated to move the tire gripping members away from each other to diminish the size of the loop in the strap to squeeze the tire about its tread thereby seating the beads of the tire on a rim associated therewith.
