Pneumatic tire with tread gauge of 95 mm or more having circumferential thin grooves, crosswise thin grooves and sub-thin grooves being closed at time of tread contact of fixed load

摘要

A pneumatic tire includes a column of center blocks (18) partitioned, on a tread center region, by circumferential thin grooves (14) formed along a tire circumferential direction and crosswise thin grooves (15) formed along a tire width direction, and columns of shoulder blocks (19) partitioned by the circumferential thin grooves (14) and main lug grooves (16) on shoulder portions. Each of the center blocks (18) includes one or more sub-thin grooves (17), each of which has a length of 100 to 180% of a circumferential length of the center block (18).
