PNEUMATIC TIRE

A tread surface (2) of a pneumatic tire is divided by vertical grooves (3a, 3b) on both sides of the tire equator into central land portions (4i), intermediate land portions (4m), and shoulder land portions (4o). The intermediate land portions (4i) have inclined grooves (9). Angle ¸ of an inclined groove (9) to the circumferential direction of the tire is increased from an inner edge (mi), away from an inner vertical groove (3a) by distance La, to an outer edge (mo) where the inclined groove (9) intersects an outer vertical groove (3b). Angle ¸i at the inner end (mi) is set to 0-25° and the angle ¸o at the outer end (mo) is set to 60-80°. A circumferential interval (P1) of inclined grooves (9) is made larger than a circumferential interval (P2) of lug grooves (5) in the shoulder land portions (4o).
