Proposed a method for determining the parameters of rectangular tires in the steady state at sinusoidal current. Thus calculated resistance, internal inductance and heat transfer coefficient, which are given surface effect, frequency sinusoidal current, material of tires, its temperature and the ambient temperature. The developed method was obtained on the basis of equations of the electromagnetic field, which can be programmed, for example, in Mathcad for computer-aided engineering design parameters of rectangular tires. The resistance and the heat transfer coefficient increases at increasing frequency of current, with internal inductance of the tire decreases. With an increase in the conductivity of the material tires decreases resistance and internal inductance. With an increase in the permeability increases the resistance, internal inductance and heat transfer coefficient. For a flat tires the resistance, inductance and internal heat transfer coefficient is less, than for the tire with a square section. The accuracy of the method is confirmed by a satisfactory agreement between the calculation of resistance and inductance with the results, obtained by means of computer simulation program Elcut.
