Tire for Vehicle, Comprising a Tread Comprising a Plurality of Compounds and a Radial Carcass Reinforcement formed of at Least Two Layers

A tire for motorized two-wheeled vehicle, comprising a radial carcass reinforcement formed of at least two layers of reinforcing elements, at least one of which is anchored by being turned up around a bead core on each side of the tire inside a bead, each bead being continued radially outwardly by a sidewall, the sidewalls being joined radially outwardly to a tread, and comprising underneath the tread a crown reinforcement structure comprising at least one layer of reinforcing elements, wherein at least the tread surface comprises a first polymeric compound extending in at least the region of the equatorial plane and at least one second polymeric compound having physicochemical properties different from those of said first polymeric compound, and wherein the density of reinforcing elements in the radially inner carcass reinforcement layer is less than that in the radially outer carcass reinforcement layer.
