VEHICLE TIRE COMPRISING A TREAD CONSISTING OF A PLURALITY OF COMPOUNDS AND A RADIAL PLY CARCASS REINFORCEMENT CONSISTING OF AT LEAST TWO LAYERS

摘要

The invention relates to a tire (1) for a two-wheeled motor vehicle comprising a radial ply carcass reinforcement consisting of at least two layers (2, 3) of reinforcing elements (10, 11), and comprising, beneath the tread (6), a crown-reinforcing structure consisting of at least one layer (7) of reinforcing elements. According to the invention, at least the surface of the tread consists of a first polymeric compound (61) extending at least into the area of the equatorial plane, and at least one second polymeric compound (62) having different physico-chemical properties from those of said first polymeric compound, the density of the reinforcing elements of the inner radial ply carcass reinforcement layer (2) being lower than that of the outer radial ply carcass reinforcement layer (3).
