PROBLEM TO BE SOLVED: To provide a pneumatic tire for improving groove wandering resistance in the tire with peripheral directional grooves formed on a tread surface. SOLUTION: The pneumatic tire forms a plurality of land parts 4 partitioned by a main groove 2 extending in the tire peripheral direction Y on the tread surface 1. A chamfer 2s is formed on the opening end 2a of the main groove 2, and a width (w) of this chamfer 2s is periodically changed in the tire peripheral direction Y. COPYRIGHT: (C)2007,JPO&INPIT |
