<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire to suppress uneven wear in the tire width direction outside and inside each block and rib. <P>SOLUTION: In the block 11, lateral direction load becomes larger in a portion as the width direction outside a vehicle than that in a portion as the width direction inside the vehicle when mounting the tire in the vehicle. Each sipe 12 and 13 is provided so that the rigidity on tire width direction one end side (the width direction outside of the vehicle) of the block 11 may be higher than the other end side (the width direction inside of the vehicle), and thereby each sipe 12 and 13 has advantages of suppressing the uneven wear in the tire width direction outside and inside each block 11 and preventing braking performance on a wet road surface and an on-ice road surface from considerably being lowered, even if wear develops. Further, the wear of the block 11 is uniformed, reducing rolling resistance with improved low fuel economy. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
