In this pneumatic tire, first lug grooves (322A) each have one end that opens into the edge of an inside second land portion (32) towards the tire ground end T-side and another end that is terminatedin the interior of the inside second land portion (32), and second lug grooves (322B) each have one end that opens into the edge of the inside second land portion (32) towards the tire equatorial plane CL-side and another end that is terminated in the interior of the inside second land portion (32). The first lug grooves (322A) and the second lug grooves (322B) are arranged alternately in the tirecircumferential direction. Meanwhile in a region on the outside in the vehicle width direction a circumferential main groove (23), which is located towards the tire equatorial plane CL-side so as todefine an outside second land portion (34), has a bent shape with amplitude in the tire width direction and has a bent portion with a sharp bend angle on the edge of the tire equatorial plane CL-side.The outside second land portion (34) is provided with lug grooves (341) opening at a position facing the bent portion.
