Abstract
A pneumatic tire has two circumferential-direction main grooves () and lug grooves (). The circumferential-direction main grooves are disposed outside quarter point sections of a tread contact width (TW) in a tread width direction, respectively, the two circumferential-direction main grooves extending in a tire circumferential direction, each of the quarter point sections of the tread contact width (TW) being a midpoint between a tire equator line and a corresponding tread end portion. The lug grooves are extended outwardly from the circumferential-direction main grooves in the tread width direction. Each quarter point section of the tread contact width (TW) has a rib-like shape continuously extending in the tire circumferential direction.
