Fast road motor vehicle of which at least each of the front wheels is provided with a plurality of pneumatic tires. The periphery of the rim (1) has three profiles (2a, 2b, 2c), each of which allowing to mount one pneumatic tire (3a, 3b, 3c). The ratio height/total width of the assembly formed by using three pneumatic tires (3a, 3b, 3c) of a normal type, corresponds to the ratio height/width of a single pneumatic tire having a large cross-section. The invention allows to improve the road holding of the vehicle at high speeds, particularly on a slippery road. Furthermore, the risk of accidents in case of a puncture or the blow out of a tire is reduced and it is not necessary to change the wheel on the spot.
