Abstract

An object the present invention is to provide a tire, in which wear resistance has been enhanced by optimizing the shape and location of block land portions. The tire has plural rowsof block land portionsformed by demarcation by providing plural circumferential groovesextending along tire circumferential direction and plural lateral groovesfor communicating adjacent two circumferential grooveswith each other; in at least two rowsof block land portions adjacent to each other with a circumferential groove therebetween, among the rowsof block land portions, the respective rowsof block land portionsare disposed to be offset with respect to each other in the tire circumferential direction. The extending direction of the groove portionbetween the block land portions adjacent to each other in the tire widthwise direction is inclined with respect to the tire widthwise direction and tire circumferential direction. A distance between the block land portions adjacent to each other in the tire widthwise direction dis shorter than a distance dbetween the block land portions adjacent to each other in the tire circumferential direction.
