ABSTRACT:
A radial ply tire (10) has a belt assembly (21) of at least one, and preferably two, belt plies (22, 23). At least one of the belt plies has a gum strip laying flat against a belt edge or folded over the edge of a belt ply such that there is at least one reinforced gum strip on each lateral side of the belt assembly. The reinforced gum strip comprises parallel reinforced cords encapsulated in gum treatment of 0.015 to 0.55 total gauge, wherein the reinforcing cords make an angle of 5.degree. to 90.degree. with respect to the equatorial plane (EP) of the tire.
