Abstract
Plural lug grooves are formed that extend from an outermost circumferential direction groove towards a tire equatorial plane side and are disposed sloped with respect to the tire equatorial plane at intervals along the tire circumferential direction. Arc shaped communication grooves are formed in segment land portions arising from a land portion being segmented in the tire circumferential direction by the lug grooves. The communication grooves communicate between the lug grooves adjacent to each other in the tire circumferential direction.
