Abstract
The deformation of a loaded bike tire has been analyzed with a model consisting of a toroid of thin inextensible walls mounted on a central rim. If the tire radius is much shorter than the rim radius, the deflection, d, of the tire can be calculated as a function of the applied load, F. The solution can be approximated to a power law dependennce F proportional to d^(3/2) for small loads. The theoretical predictions compare well with the experiments carried out on two bicycle tires.
