PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving uneven wear resistance while securing traction performance after a middle stage of wear.SOLUTION: Six to eight major grooves continuously extending in a tire circumferential direction, and a plurality of land parts partitioned by the major grooves are provided on a tread surface Tr. Inside mediate land parts 23 and center land parts 24 are each partitioned into a plurality of blocks by lateral grooves 3 and 4. The lateral grooves 3 and 4 include: a pair of wide parts 31 and 41 whose widths are relatively wide, and which are opened to the major grooves 12 and 13; and narrow parts 32 and 42 whose widths are relatively narrow, and which connect the pair of the wide parts 31 and 41. One-side closed sipes 30 opened on the wide parts 31 and closed on the narrow parts 32 are formed on the bottoms of the lateral grooves 3 provided on the inside mediate land parts 23, and both-side opened sipes 40 opened on the wide parts 41 and the narrow parts 42 are formed on the bottoms of the lateral grooves 4 provided on the center land parts 24.SELECTED DRAWING: Figure 1 |
