摘要： A motorcycle tyre comprises a tread portion (2) curved convexly such that the maximum cross section width TW of the tyre lies between the tread edges (E), a carcass ply (6) of cords arranged radially at an angle of 70 to 90 degrees to the tyre equator, and a belt ply (7) of at least one cord laid at an angle of 0 to 35 degrees disposed radially outside the carcass ply (6) in the tread portion. When the tyre is mounted on a standard rim and inflated from 10 % of a standard inner pressure to 100 % thereof, the tread portion swells such that the amount of swelling is larger in a shoulder region than a crown region of the tread portion. The carcass cord tension Tcs in the shoulder region is 2.0 to 3.8 times the carcass cord tension Tcc in the crown region, and the belt cord tension Tbs in the shoulder region is 1.2 to 2.0 times the belt cord tension Tbc in the crown region.
