PURPOSE:To provide a two wheeler pneumatic tire excellent in high-speed durability and used for two wheelers presented to a race, having a high griping performance when turning traveling on a dry road. CONSTITUTION:In a pneumatic tire for a motor-cycle presented to a race on a dry road, treads are divided into sections by arranging grooves in an arranging angle of 0 to 60 degrees against the tire circumference in the central area between tread 1/4 points apart from the tire equator to the tread 4 end direction by 1/4 times of the periphery length between tread 4 ends, while other areas being slick tire, the bending rigidity of the tread 4 part can be rationalized to a simplified structure by the grooves and high-speed durability can be provided, while high gripping capability when turning at high speed can be prepared. |
