More Information
Summary:The invention relates to a tyre having a radial carcass reinforcement formed by a single layer of reinforcing elements which is anchored in each of the beads, being turned up around a bead wire, and reinforced by a stiffener. According to the invention, a sixth layer of one or more polymer blends (21) is radially inside the end (8) of the turn-up (7) of the carcass reinforcement layer and axially between the turn-up (7) of the carcass reinforcement layer and the main part of the carcass reinforcement layer (2), the maximum tan(δ) value of the sixth layer of one or more polymer blends (21), denoted tan(δ)max, measured at 60° C, being less than 0.050 and the linearity ratio of the dynamic complex shear modulus G* of the sixth layer of one or more polymer blends (21), at a temperature of 23° C, being greater than 0.80.
