Abstract
A bias ply pneumatic tire 40,80 is disclosed. The tire 40,80 has a tread 42,82 with a plurality of circumferentially continuous grooves 52,72 and a plurality of laterally extending grooves 50,70. The grooves define tread elements 60,90 of parallelogram shape. Each lateral groove 50,70 includes a portion 53,73 extending from a tread edge a distance of at least 5% of the tread width (W). The portion of the groove 53,73 adjacent a tread edge is inclined less than 25.degree. relative to a plane passing through the axis of rotation, preferably inclined 23.degree.. The tread elements 60,90 preferably have radially extending groove walls having an outer portion 69A,79A inclined at 10.degree. and an inner portion 69B,79B inclined at least 30.degree. relative to the radial direction. The tire is particularly well-suited for a rear drive tire for Sprint car racing vehicles.
