Latest Patents

One of his latest patents is for a tread with an improved drainage space. This tire tread band features a tread surface with at least two wearing layers. The first wearing layer is formed by raised elements, each having a contact surface and grooves of circumferential orientation. This design is intended to contact the road surface when new. Additionally, there is at least one wearing layer that comes into contact with the road surface after the first layer has completely worn away. This layer contains at least one channel extending in the circumferential direction, which opens onto the tread surface when the preceding wearing layer has entirely worn away. Each wearing layer is distinct from the first, featuring transverse incisions distributed in the circumferential direction. These incisions extend from a channel of the layer in a non-circumferential direction, opening fully or partially into at least one other circumferentially oriented channel or groove, regardless of the wear level of the other wearing layer.

Another significant patent by Barraud is for a tire with an improved carcass. In this design, the reinforcing cords of the carcass, located between the anchoring zone and the sidewall, are in contact with at least one layer of cushion compound. This compound has a high modulus of elasticity on the axially outer side and a low modulus of elasticity on the axially inner side and in the sidewall.
