A vehicle wheel has at least two pneumatic tires mounted side by side on a single rim. When the weight of the vehicle is applied to the wheels, the pneumatic tires are slightly deformed in the lower portion of their circumference, their facing side walls coming to bear one against the other. In the upper portion of their circumference, the pneumatic tires remain separated from one another. This provides the best possible cooperation of the pneumatic tires, completely avoiding the overheating thereof and improving the road-holding of the vehicle and the adhesion of the wheels on a slippery road surface. |
