A tread pattern of a pneumatic tire includes: first and second circumferential main grooves; a first circumferential narrow groove between the first and second circumferential main grooves, the first circumferential narrow groove having a narrower width than the first and second circumferential main grooves; an intermediate lug groove extending from the second circumferential main groove toward the first circumferential narrow groove, the intermediate lug groove being closed without reaching the first circumferential narrow groove; and a sipe extending from the closed end of the intermediate lug groove to connect the closed end with the first circumferential narrow groove. No lug grooves are between the first circumferential main groove and the first circumferential narrow groove, and a groove wall of the first circumferential main groove on a side of the first circumferential narrow groove circumnavigates without interruption in the tire circumferential direction.
