ABSTRACT:
A tread pattern for a pneumatic tire having a plurality of circumferentially extending zig-zag and straight longitudinal grooves and a multiplicity of transverse grooves extending generally axially and joining the longitudinal grooves to define a block pattern.
The tread pattern will change from a block pattern to a rib pattern as it wears because the transverse grooves extend to a shallower depth than the longitudinal grooves. The bottom of the longitudinal grooves, which are at a greater depth, preferably have a different zig-zag pattern than the part of the longitudinal groove which contact the road when the tire is new.
