Abstract
A tire comprising at least one reinforcement structure of carcass type anchored on either side of the tire in a bead, the base of which is intended to be mounted on a rim seat, each bead being extended radially outward by a sidewall, the sidewalls extending radially towards outward to join a tread, the reinforcement structure extending circumferentially from the bead towards said sidewall, an anchoring zone for the reinforcement structure, said tire furthermore comprising an anti-vibration means arranged circumferentially in the junction zone of the shoulder and the sidewall.

A tire for a two-wheeled vehicle, comprising:
- at least one reinforcement structure of carcass type anchored on either side of the tire in a bead the base of which is intended to be mounted on a rim seat, each bead being extended radially towards the outside by a sidewall, the reinforcement structure extending circumferentially from the beads towards said sidewalls, the sidewalls extending radially outward to join a tread and said tread forming a crown, said tread having a height Ht and a width Wt, wherein a ratio Ht/Wt is greater than 0.15;
- an anchoring zone for the reinforcement structure,
- a transition zone corresponding substantially to the change from the lateral portion of the tread to the sidewall;
- an anti-vibration means arranged circumferentially in said transition zone and extending radially substantially radially outward towards said crown and extending substantially radially inward in said sidewall;
- said anti-vibration means comprising at least one alignment of substantially circumferential cords.
A method to reduce the generation of shimmy type vibrations in a tire for a two-wheeled vehicle comprising the steps of:
- providing a tire comprising at least one reinforcement structure of carcass type anchored on either side of the tire in a bead the base of which is intended to be mounted on a rim seat, each bead being extended radially outward by a sidewall, said sidewalls extending radially outward to a tread and said tread forming a crown, and said tread having a height Ht and a width Wt, wherein a ratio Ht/Wt is greater than 0.15, the reinforcement structure extending circumferentially from the beads towards said sidewalls, said tire also comprising a transition zone corresponding substantially to the change from the lateral portion of said tread to said sidewall,
- arranging an anti-vibration means circumferentially in said transition zone and extending substantially radially outward towards said crown and extending substantially radially inward in said sidewall.
