A pneumatic tire having a tread pattern appropriately formed to improve heat dissipation properties, wear resistance, and uneven wear resistance. The pneumatic tire has arranged in a tread (2) two circumferential fine grooves (10) disposed on opposite sides of the tire's equatorial surface (CL) and extending in the tire's circumferential direction, 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 tire's 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 tire's circumferential direction from the other end of the first small groove (13) toward the other circumferential fine groove.
