PNEUMATIC RADIAL TIRE

摘要

A pneumatic tire is provided herein having tread blocks provided in the side walls with grooves open at the top of the block. The depth (gW) of each groove in the axial direction of the tire is in the range of 5 to 50% of the block width (BW). The width (gL) of each groove in the circumferential direction is in the range of 5 to 25% of the block length (BL). The height (gH) of each groove at the block side wall is in the range of 15 to 80% of the depth (GH) of a main groove dividing the block. Because of these characteristics of the grooves, performances on snowy and icy roads, and noise generation and wear resistance on normal roads are each improved in good balance.
