ABSTRACT:
A pneumatic tire has one or more radial plies formed of cords of reinforcing material which extend continuously between the two bead regions of the tire within the side walls and tread region. Belts of reinforcing material extend circumferentially within the tread region with a plurality of the belts being situated inside the portion of the radial ply which is within the tread region. Successively more inward ones of the belts are of progressively greater width enabling the lateral edges of each belt to be situated adjacent the inside surface of the radial ply and relatively remote from the edges of adjacent belts. With the edges of the belts thus located, the stress riser effect is reduced and there is less tendency for the belt edges to peel away from the radial ply when the tire is subjected to cornering forces. Belt separation is thereby inhibited and the reliability and durability of belted radial-ply tires is enhanced.
