Patent ID: 6988520

Claim:
A motor-cycle tyre ( 1 ) comprising a ground contacting tread ( 2 ) reinforced between its edges ( 3 , 4 ) by a breaker assembly and having in its normally inflated fitted condition a camber value C/L of between 0.5 and 0.7, a reinforcing carcass ply ( 14 ) extending radially inside the breaker assembly and between two bead regions ( 10 , 11 ) and wrapped in each bead region around an annular bead core ( 12 , 13 ) from the axial inside to the outside to form carcass ply turn-ups ( 15 , 16 ) and between the tread edges ( 3 , 4 ) and bead regions ( 10 , 11 ), tyre sidewalls ( 8 , 9 ) wherein the breaker assembly comprises two breaker plies ( 5 , 7 ) comprising reinforcing cords oppositely inclined with respect to the circumferential direction of the tyre characterised in that the tread comprises two different rubber compounds, a first rubber compound extending in a continuous first layer between the tread edges ( 3 , 4 ) and a second rubber compound disposed in a second layer radially outwardly of the layer of the first rubber compound to form the tread running surface in the central portion of the tread, centered on the tyre axial centreline, having a width (S) of between 30% and 50% of the tread width (TW), the widths being measured along the arc of the tread surface and an interfacial fabric layer comprising reinforcing cords disposed at the boundary between the first and second rubber layers, the cords of the fabric layer are laid parallel to each other and disposed at an angle of 18°–30° to the tread circumferential direction and radial thickness of the second layer of rubber is between 50% and 80% of the total radial thickness of the tread.
