Tru-Flate reinforced unitized tire boots are for use on tube type tires when a puncture, gash or split in the tire creates a potential spot for the tube to be pinched or push through the tire. The Boot covers this damaged area preventing any possible pinching or push through problems from occurring. Tru-Flate boots feature right angle cord construction that utilizes high tensile strength cords. These boots wont dry out or self-cure. Can be used with cement or a spotter. Tru-Flate is part of the Plews & Edelmann group. Plews manufacturing and sales Corporation was originally founded by R. G. Plews in 1927.
