ABSTRACT:
A tire repair plug that is stretched in an insertion tool and inserted into a bored-out tire injury. The plug includes a cylindrical stem and a conical head disposed at the leading end of the cylindrical stem. A circular transverse opening is located slightly axially interior to the leading end of the cylindrical stem. A bearing surface is located at the bottom of the transverse opening to prevent the plug from sliding off the insertion tool. A transverse slit extends from the transverse opening to a trailing end of the stem and bisects the cylindrical stem into two halves with semi-circular cross-sections. The two halves have adjoining inner walls. Disposed along the outside of the cylindrical stem and along the inner walls is cushion gum sheet. A protective covering is disposed along the outside of the cushion gum sheet until the plug is ready for use.
