<p>A tread pattern of a pneumatic tire includes a plurality of inclined lug grooves, each having an opening end open into one of two circumferential grooves and a terminal end closed in a land portion sandwiched between the circumferential grooves. Each of the inclined lug grooves extends in a first direction of the tire circumferential direction from the opening end. The tread pattern further includes narrow grooves, each having a starting end at a midpoint of each of the inclined lug grooves. Each of the narrow grooves extends in a second direction opposite to the first direction, and is closed in the land portion. Each of the inclined lug grooves has a curve portion and a straight portion between the opening end and the terminal end. The straight portion extends parallel to the tire circumferential direction and includes the terminal end. The closed end of the narrow groove is positioned on a side of the second direction of the tire circumferential direction with respect to the terminal end of an inclined lug groove adjacent in the second direction to each of the inclined lug grooves.</p> |
