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.
