A tread pattern of a pneumatic tire is formed by arranging lateral grooves (3a, 3b, 3c) in a tread and combining at least two kinds of pitch segments having different pitch lengths (P1, P2, P3) in the ciricumferential direction of the tread and each having a negative ratio of 25-55%. In this tread pattern, a distance (R) from the tire center to a land surface at a tire section in the circumferential direction under inflation of air pressure is made longer as the pitch length in the pitch segment becomes shorter. <IMAGE> |
