<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire in which heal-and-toe wear resistance is improved. <P>SOLUTION: The pneumatic tire includes a plurality of blocks 1 formed by dividing by a plurality of circumferential main grooves 10 which extend to a tire circumferential direction, and a plurality of lug grooves 20, 20' which extend to a tire width direction. In the pneumatic tire, the block 1 includes a concave section 4 which is arranged on a wall face at one lug groove 20 side, and opens to both wall faces to the circumferential main groove 10, and thereby, there is a rigidity difference between an end of one lug groove 20 side and an end of the other lug groove 20' side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
