<p>A pneumatic tire (1) for a motorcycle, capable of improving both of lightness of handling and stability during braking by means of optimizing the pattern arrangement, has a tread portion (5) provided with at least a pair of circumferential grooves (7) extending generally in a circumferential direction of the tire and oppositely disposed with respect to an equatorial plane (CL) of the tire and a plurality of inclined grooves (8) extending from an outer side to an inner side in a width direction on a grounding surface of the tread portion to be inclined with respect to the circumferential direction of the tire and ended within the grounding surface of the tread portion. The circumferential grooves (7) are disposed in the side areas (10) when the tread portion (5) is divided into a central area (9) and two side areas (10) located at both sides on the central area (9). The inclined grooves (8) slanting in mutually opposite directions with respect to the circumferential direction of the tire are alternatively arranged along the circumferential direction of the tire. At least some of the inclined grooves (8) extend across the equatorial plane of the tire.</p> |
