Abstract
The present invention relates to the field of tires having reinforced sidlls. In order to improve the high-speed performance of a tire and reduce the extent of vibration of the sidewalls (1) and effectively transmit a torque from the wheel to the ground via the tire, the rigidity of the sidewalls of the tire is adjusted by the provision of reinforcements (6) in the form of assembly sections oriented in circumferential direction. Said assembly sections are of short length as compared with the development of the tire measured at the point S of the tire which is located furthest radially to the outside.
Claims8
A tire having two sidewalls extended radially towards the outside by a crown having a tread and radially towards the inside by beads, each sidewall having at least one carcass reinforcement and at least one of said sidewalls having circumferentially oriented reinforcements which are coupled mechanically to said carcass reinforcement, characterized by the fact that said sidewall reinforcements are formed of groups comprising one or more sections of assembly, said sections having a length less than 1/10th of the circumference, measured at the point of the crown furthest radially to the outside, each group being coupled, in the neighborhood of each of its two ends, to at least one other group of sections.
