Abstract
A pneumatic tire is configured so that half-tread regions on both sides in the widthwise direction of the tire are provided with: a wave-shaped circumferential main groove group including outer circumferential main grooves and an inner circumferential main groove; land sections; and lug grooves, sipes, or lug groove and sipe combinations formed by combining lug grooves and sipes. The lug grooves are configured in such a manner that, in the half-tread region on the first side, wave-shaped crests are connected at both ends of the land section in the widthwise direction of the tire, and in such a manner that, in the half-tread region on the second side, wave-shaped troughs are connected at both ends of the land section in the widthwise direction of the tire.
