A pneumatic tire exhibiting high traction performance. A center circumferential groove (14) is provided on the equator (CL) of the tread (12), and between shoulder circumferential grooves (18) on both sides of the center circumferential groove (14) are arranged first lateral grooves (20) and second lateral grooves (22) formed at a smaller angle relative to the axial direction of the tire than the first lateral groove (20). One end of each first lateral groove (20) and one end of each second lateral groove (22) are made to merge at a shoulder circumferential groove (18), and shoulder lateral grooves (23) are arranged on the outer side of each shoulder circumferential groove (18). Each shoulder lateral groove (23) extends from the merging portion toward a tread end (12E) and is formed at a smaller angle relative to the axial direction of the tire than that of the first lateral groove (20). Because the angle of the shoulder lateral grooves (23) relative to the axial direction of the tire is less, traction performance of the tire increases.
