Abstract
Abstract A tire suitable for all types of wheels, including vehicles and wheels, such as in automobiles, motorcycles or bicycles, in which the tire body is an extruded or molded plastic material formed in indeterminate length complete with conventional tread and shape means to fit the usual rim of a wheel. The tire is completed by cutting a length from the indeterminate length of tire body equivalent to the rim size of the wheel for which it is intended, then bonding the ends together. The finished tire may then be stretched and snapped on the wheel frame or rim.
