A pneumatic tire for a bicycle in which turning performance on a wet pavement is enhanced as compared with that of a conventional tire. Assuming the region of 60% of the development width of a tread (28) with the equatorial plane CL of the tire as the center is a tread central portion and the outside of the tread central portion in the direction of tire width is a tread side portion, 100-200 narrow inclination grooves (44) are formed in the circumferential direction of the tire in the tread side portion, and negative rate is set in the range of 5-20%. Consequently, both drainage performance and block rigidity can be satisfied at a high level at a ground contacting portion during turning, and a higher grip force than before can be attained during turning on a wet pavement. |
