text: As an example of the pneumatic radial tire of the invention, if a cord having high elastic modulus is used for the belt layer and a cord having low elasticity such as nylon is used for the carcass layer, when the standard internal pressure is charged, the growth in the radial direction is suppressed by the high elastic cord, and since the tire relatively freely swells in the widthwise direction of the tire, the falling-down of the bead portion becomes greater as compared with a conventional tire.
