A pneumatic tire has a tread pattern designed to provide improved heat dissipation properties, wear resistance, and uneven wear resistance. The tire has arranged in a tread (2) two circumferential fine grooves (10) disposed on opposite sides of the equatorial surface (CL) of the tire and extending in the circumferential direction of the tire, and the circumferential fine grooves (10) define a center land section (11). In the center land section (11) are formed oblique fine grooves (12) each having a first small groove (13) extending in the tire's circumferential direction, a second small groove (14) extending obliquely relative to the circumferential direction from one end of the first small groove (13) toward one circumferential fine groove, and a third small groove (15) extending obliquely relative to the circumferential direction from the other end of the first small groove (13) toward the other circumferential fine groove.
