<P>PROBLEM TO BE SOLVED: To provide a tire effectively suppressing uneven wear of block parts with treads to be grounded on a road surface. <P>SOLUTION: The tire includes a plurality of circumferential grooves extending in zigzags along a circumferential direction of the tire, a plurality of lateral grooves extending in a width direction of the tire, and the block parts formed by circumferential grooves and lateral grooves. Each block part is formed to become wider in the width direction toward the center from the outside in the circumferential direction of the tire. A circumferential sidewall angle formed by a circumferential sidewall surface formed on the block part by the circumferential grooves and the tread changes to be an obtuse angle at an end formed on the tire circumferential block part and to be an acute angle at the other end of the tire circumferential direction. A width direction sidewall angle formed by a width direction sidewall surface formed on the block part by the other lateral grooves and the tread changes to be an obtuse angle to an acute angle toward the circumferential sidewall surface. <P>COPYRIGHT: (C)2013,JPO&INPIT |
