ABSTRACT:
A pneumatic tire (10) has a tread portion (11) comprising a plurality of circumferentially extending grooves (21,22,23) which divide the tread into axially spaced lands (24,25,26,27). Each land is subdivided into blocks (32X,32Y) by cross-slits (31). The blocks in each land (24,25,26,27) are arranged so that circumferentially adjacent blocks (32X,32Y) are axially offset relative to each other. The cross-slits (31A,31B,31C) in each land alternate circumferentially between axially extending cross-slits (31B) and biased angle cross-slits (31A,31C). The axially extending cross-slits (31B) are sipes and the biased angle cross-slits (31A,31C) may be either sipes or grooves.
