A tire repair insert having a body defined by a pair of ends, a pair of parallel sides, and a pair of edges, with one of said edges being tapered from one of the ends to the other of the ends such that the cross-sectional area of the body increases from a minimum at one end, to a maximum at the other end. The body includes a pair of outer layers of semi-cured rubber, and an intermediate layer of semi-cured rubber. A layer of cured rubber is positioned between the intermediate layer and each of the outer layers. The rubber layers are free of any internal reinforcement and have an elongation factor of approximately 600%. In a method for repairing tires with the above described tire repair insert, a technician first observes the puncture within the tire. If the puncture is small, then the smallest cross-sectional portion of the tire repair insert is placed within an eye of an end slot needle. If the puncture is intermediate in size, then the tire repair insert is positioned within the eye of the end slot needle such that each of the ends is equidistance from the end slot needle. Lastly, if the puncture is large, than that portion of the tire repair insert having the largest cross-sectional area is inserted into the eye of the end slot needle. In this manner, when the needle and tire repair insert are inserted into the puncture, the mass of elastomeric sealing material extending into the puncture matches the puncture size and reduces the amount of force required for insertion of the insert into the puncture.
