Patent ID: 8881779

Claim:
A pneumatic tire in which a plurality of land portions defined by main grooves extending in a tire circumferential direction are formed in a tread surface, and in which both side walls of each of at least two land portions of the plurality of land portions are provided with a plurality of dent parts formed at certain intervals in the tire circumferential direction, each of the dent parts having a smaller depth than the main grooves defining the land portion where the dent part is formed, a plurality of sipes, each formed to traverse in a tire width direction between the dent parts formed in both the side walls of the land portion, each of the dent parts having an upper base which extends in the tire circumferential direction, a first one of the sipes extending from a first location at an upper base of a first one of the dent parts to a first location at an upper base of a second one of the dent parts, and a second one of the sipes extending from a second location at the upper base of the first one of the dent parts to a second location at the upper base of the second one of the dent parts without crossing the first one of the sipes, the first and second locations at the upper base of the first one of the dent parts being spaced from each other in the tire circumferential direction and the first and second locations at the upper base of the second one of the dent parts being spaced from each other in the tire circumferential direction, each of the sipes having a greater depth in both end regions opening to the dent parts than in a center region between both the end regions, and the land portion where the dent parts are formed in both of the side walls has a lug groove formed between each two of the dent parts adjacent in the tire circumferential direction and is formed as a block row, the lug groove being inclined with respect to the tire width direction and extending to an inside of an other one of the land portions next to the land portion, a portion of the lug groove inside the other one of the land portions having a tip bent end in a dogleg shape, and the other one of the land portions including at least one sipe formed to traverse an area between the dogleg shaped tip bent end of the lug groove and the main groove formed between the land portion and the other one of the land portions.
