The present invention relates to pneumatic tires comprising a dual-layer tread made of a first layer comprising a first tread compound having a first tread property and a second layer comprising a second tread compound having a second tread property.

Tire comprising a dual-layer tread

A rubber composition comprising 50 phr to 100 phr of a styrene butadiene rubber; 0 phr to 50 phr of at least one diene based rubber; 95 phr to 200 phr of filler comprising i) 50 phr to 100 phr of silica, ii) 40 phr to 70 phr of carbon black and iii) 5 phr to 30 phr of an inorganic metal hydroxide; 40 phr to 80 phr of plasticizer comprising a hydrocarbon resin having a softening point within a range of 80° C. and 130° C.

Rubber composition and a tire comprising a rubber composition

A motor-cycle tire () comprising a ground contacting tread () reinforced between its edges () 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 () extending radially inside the breaker assembly and between two bead regions () and wrapped in each bead region around an annular bead core () from the axial inside to the outside to form carcass ply turn-ups () and between the tread edges () and bead regions (), tire sidewalls () wherein the breaker assembly comprises two breaker plies () comprising reinforcing cords oppositely inclined with respect to the circumferential direction of the tire characterized in that the tread comprises two different rubber compounds, the first rubber compound extending in a continuous first layer between the tread edges () and the second rubber compound being 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.
