Motorcycle belted tire excellent in grounding characteristic

Abstract

Abstract PURPOSE:To improve wet performance of the captioned tire, its driving stability and driving feeling or the like, by specifying length and width of many blocks formed in a tread and forming in each block many cuts arranged on the basis of a lateral direction. CONSTITUTION:A tire, in which a pair of side walls and treads are reinforced by a carcass consisting of a cord ply rarranging an organic fiber cord at an angle of 50 deg.-90 deg. for an equatorial surface of the tire further a belt consisting of a cord layer arranging an unextensible cord similarly at an angle of 30 deg. or less is arranged between the tread and the carcass, forms many blocks 13, divided by a peripherally directional groove 12 and a transverse groove 11, in the tread. Each block 13 is formed so as to provide a length 30-70% of the length that the tire is grounded when it receives a normal load while a width corresponding to a size about 1-1/2 times that length. While each block 13 forms many cuts on the basis of a lateral direction.
