Abstract
A pneumatic tire includes a tread surface which is sectioned into a center area, a mediate area arranged in an outer side of the center area, and a shoulder area arranged in an outer side of the mediate area, wherein inclined grooves are formed spaced apart in a tire circumferential direction, the inclined grooves continuously extending from the mediate area to the shoulder area, in blocks in the mediate area and the shoulder area sectioned by the inclined grooves, an angle of inclination of a side wall on a leading side with respect to a normal direction of the tread surface is greater than an angle of inclination of a side wall on a trailing side with respect to a normal direction of the tread surface, and a plurality of dimples are formed in the side wall on the leading side of the block in the mediate area.
Claims3
A pneumatic tire comprising:
- a tread surface which is sectioned, by a plurality of circumferential grooves extending in a tire circumferential direction, into a center area including a tire equator, a mediate area arranged in an outer side in a tire width direction of the center area, and a shoulder area arranged in an outer side in the tire width direction of the mediate area, wherein
- a plurality of inclined grooves are formed spaced apart in the tire circumferential direction, the inclined grooves continuously extending from the mediate area to the shoulder area while being inclined to an outer side in the tire width direction toward a rear side in a tire rotating direction,
- in blocks in the mediate area and the shoulder area sectioned by the inclined grooves, an angle of inclination of a side wall on a leading side with respect to a normal direction of the tread surface is greater than an angle of inclination of a side wall on a trailing side with respect to a normal direction of the tread surface, and
- a plurality of dimples are formed in the side wall on the leading side of the block in the mediate area.
