ABSTRACT:
An improved belt structure, particularly suited to steel belted radial truck tires for highway use comprises providing at least one corrugated belt in combination with a flat belt and a hard rubber layer sandwiched therebetween. The corrugations comprise radially inward depending, circumferentially extending depressions in at least one belt. The depressions are radially aligned with the grooves in the tire tread, and thereby form arches to transfer stress away from the portion of the tread underlying the grooves to the solid portion of the tread between grooves. The improvement of the invention is believed to reduce or eliminate excessive wear and nipping of tread corner edges adjacent the tread grooves.
