ABSTRACT:
A pneumatic tire having a generally trapezoidal section and sidewalls which are predominantly under compression under load is provided with non-reinforced sidewalls made of an elastomeric composition having a dynamic modulus of elasticity between 8 and 13 megapascal units and the tangent of the loss angle is between 0.03 and 0.15. By controlling the ratio between the absolute value of the modulus and the relative loss angle, the tire has optimum mechanical characteristics.
