PROBLEM TO BE SOLVED: To enhance a lateral slide resistant property. SOLUTION: A plurality of main grooves 11 extending in a circumferential direction of a tire and a plurality of land portions 13 separated by these main grooves 11 are formed on a tread surface. A plurality of lug grooves 6 extending from one edge portion to an intermediate portion of the land portions 13 along a circumferential direction A of the tire and a plurality of lug grooves 7 extending from the other edge portion to the intermediate portion are alternately formed. Inner end portion 6e, 7e of the adjacent lug grooves 6, 7 in the circumferential direction A of the tire are connected each other by two sipes 8, 9 extending in the circumferential direction A of the tire. Large land portions 15 having a large width and positioned at both outer sides of the two sipes 8, 9 and small land portions 14 having a narrower width than that of the large land portions 15 and clamped at inner sides of the two sipes 8, 9 are formed. |
