Portable motorized tire support

A tire support device for automobile racing tires is a self contained unit which can be conveniently transported and used at a race track or other location for mounting the tire for enabling a person to conveniently and easily perform various procedures on the tire, such as measuring the circumference, run out, and wear of an automobile tire or for preparing the surface of the tire. The mount includes an elongated member for elevating the tire above the ground. The tire support device further includes a mount having a rotatable member for rotating the tire while supported by the mount. A motor can be connected to the rotatable member for rotating the tire and improving the efficiency of the process. A clutch attached to the motor and to the rotatable member enables the tire to be automatically or manually rotated. The mount may be pivotally attached to the base for enabling the tire to be positioned in either a horizontal or vertical position. The tire is secured to the rotatable member by alignment pins inserted through holes in a cap and a tire base of the tire support device and through holes in the wheel of the tire.
