Patent ID: 10596856

Abstract:
In a pneumatic tire, blocks 11 each have a block width that is increased from circumferential end portions to a circumferential middle portion of the block 11 in a manner such that widthwise end portions 10 located on both ends in the tread width direction are positioned in a circumferentially intermediate portion of the block 11 and also have the maximum circumferential length that is larger than the maximum width of the block 11, thereby having, in its plan view, a polygonal contour shape that includes end sides 11a located in the circumferential end portions, and circumferential distances a and a1 between a circumferential middle position 11b of each end side 11a of the block 11 and a circumferential middle position 10a of a line L connecting the widthwise end portions 10 of the block 11 are both twice or more of the maximum depth of circumferential grooves.
