Pneumatic tire

A tread surface 2 is divided by inner and outer longitudinal grooves 3 a and 3 b located on opposite sides of the tire equator into a central land portion 4 i, intermediate land portions 4 m and shoulder land portions 4 o. The intermediate land portion 4 i includes an inclined grooves 9 having an angle theta with respect to the circumferential direction of the tire, and the angle is increased from an inner end (mi) away from the inner longitudinal grooves 3 a by a small distance La to an outer end (mo) where the intermediate land portion intersects with the outer longitudinal grooves 3 b. An angle thetai in the inner end (mi) is 0 to 25°, and an angle thetao in the outer end (mo) is 60 to 80°. A pitch P 1 of the inclined grooves 9 in the circumferential direction is greater than a pitch P 2 of lug grooves 5 provided in the shoulder land portion 4 o in the circumferential direction.
