ABSTRACT:
A belted pneumatic tire is disclosed in which an annular protuberance projects axially from the buttress region on each side of the tire. The protuberances are positioned radially inward of the tire tread and the lateral edges of the belt or breaker extend into the protuberances such that the breaker edges are removed from the vicinity of the tread-ground contact patch to thereby improve uniformity and edge separation problems. A relatively wide breaker having a low cross-sectional curvature is also utilized to thereby provide firm support to the tread and consequent improved performance characteristics.
