The aim of this paper is to determine the dependence of how temperature affects a change of the radial stiffness of a wheel, i.e. tyre. Whether the change in temperature of the wheel, i.e. tyre, may lead to a change in the control of a car due to a change in the slip angles of tyre, when turning the car. At the same time the paper deals with the issue of whether inflating a tyre with nitrogen leads to a change in the static radial deformation of a passenger car wheel.
