    摘要： Provided is a pneumatic tire in which the driving stability is improved without compromising durability.
    Provided is a pneumatic tire composed of tread portions, a pair of side wall portions extending from side portions of the tread portions to inward in the tire radial direction, and bead portions connected to the inner end in the tire radial direction of the side wall portions, which are reinforced by a carcass composed of one or more carcass plies composed of cellulose fiber cord covered with a coating rubber. The tensile modulus of elasticity of the cellulose fiber cord under a stress load of 29.4N per cord at a temperature of 180°C is 40 cN/dtex or higher, and all of the carcass cords are turned up around each bead core embedded at the pair of bead portions from the inside toward the outside of the tire.

    摘要： Pneumatic vehicle tyre comprising a carcass (3), wherein the carcass (3) has two carcass plies (31, 32), wherein each carcass ply (31, 32) has reinforcements which are arranged inside the carcass ply (31, 32) substantially parallel to each other. The problem addressed by the invention is to provide a pneumatic vehicle tyre which likewise creates a high quality impression of sufficient robustness to a viewer and, in the process, is cheaper to produce and has a reduced rolling resistance. The invention is characterised in that the product EF1 of the average modulus of elasticity of the reinforcements, as measured with an extension of 2%, of the first carcass ply (31) and the thread density of the reinforcements of the first carcass ply (31), and the product EF2 of the average modulus of elasticity of the reinforcements of the second carcass ply (32) and the thread density of reinforcements of the second carcass ply (32), satisfy the relationship EF1 > EF2.
