Belt separation-resistant tire configuration

A pneumatic tire of the form having an annular tread region and a pair of annular bead regions of lesser diameter and a pair of side wall regions each extending from a separate one of said bead regions to a separate side of said tread region, further comprising:

• a single transverse primary reinforcement ply formed of cords of reinforcing material extending continuously from one of said bead regions to the other thereof within said side wall regions and within said tread region, said primary reinforcement ply being located further from the inner surface of said tire in said tread region than in said sidewall regions
• at least one outer belt of reinforcing material extending circumferentially within said tread region of said tire and being situated radially outward from the portion of said primary reinforcement ply which extends across said tread region, and
• a plurality of inner belts of reinforcing material extending in a circumferential direction within said tread region of said tire, said plurality of inner belts being of progressively smaller diameter from the outermost of said plurality of inner belts to the innermost thereof, and being situated radially inwardly from the portion of said primary reinforcement ply which extends across said tread region, said plurality of inner belts being of progressively greater width from the outermost to the innermost thereof and wherein the lateral edges of each of said plurality of inner belts are adjacent the inner surface of said primary reinforcement ply and equidistant from said cords thereof.
