Abstract
PURPOSE:To improve the durability of the titled tire used for motorcycle, etc., by specifying the direction of the cords of a carcass and a breaker and reducing the tensile modulus of the breaker cord and uniforming the thickness of the rubber between a tread surface and the carcass side breaker ply. CONSTITUTION:A carcass 9 is formed into troidal form by arranging tire cords 6 at an angle of 70-90 deg. with respect to the tire equator and turning back said cords around a bead core 7. A breaker 12 is formed from at least one layer of the breaker ply 10 which is arranged at an angle of 10-25 deg. with respect to the tire equator, and consists of the organic fiber cords having a tensile modulus of 200-400kg/mm<2>. Further, each of the max. and min. value of the thickness D1 between the tread surface within a range of 80% of the tread surface 2 and the breaker ply 10 on the carcass 9 side is set within + or -10% of the average value. With such constitution, the exfoliation at the both edges of the breaker is reduced, and durability can be improved.
