Title: PNEUMATIC TIRE
Abstract:
To improve resistance to one-sided wear while reducing noise in a pneumatic tire 1, a tread surface 3 is provided, wherein: when the region inside of shoulder-circumferential direction main grooves 13 in the tire width direction is defined as an inner area 4, and the region outside of the shoulder-circumferential direction main grooves 13 in the tire width direction is defined as an outer area 5, blocks 20 located in the inner area 4 are each partitioned into three or more small blocks 40 by narrow grooves 30, and blocks 20 located in the outer area 5 are each partitioned into a number of small blocks 40 by narrow grooves 30, the number being smaller by at least one than the number of the small blocks 40 into which the blocks 20 located in the inner area 4 are partitioned; and the small blocks 40 that include the frontmost portions of the blocks 20 in the tire rotating direction are treading-side blocks 41, and the small blocks 40 that include the rearmost portions of the blocks 20 in the tire rotating direction are kicking-side blocks 42, the treading-side blocks 41 being smaller in surface area than the kicking-side blocks 42.
