A radial ply tire ( ) has a floating reinforcement ply on the inside shoulder/sidewall region of the tire. The reinforcement ply comprises ply rubber having a gauge sufficient to delocalize flexing in the tire shoulder/sidewall region, and in one embodiment may be reinforced with 0.50 to 6.0 phr fibers. Depending on the type of tire in which the reinforcement ply is used, the reinforcement has a total gauge of 0.005 inch to 0.175 inch (0.127 to 4.445 mm). When fiber is used in the illustrated embodiment, the fiber is oriented circumferentially in the tire.

This invention relates to the discovery that the addition of a free triacrylate, tetraacrylate and/or pentaacrylate compound(s) to an uncrosslinked rubber which is then sulfur-vulcanized results in desirable reversion resistant rubber compound properties.
