摘要： A pneumatic radial tire of the present technology has a belt reinforcing layer and a tread rubber. The belt reinforcing layer comprises a composite fiber cord having one aromatic polyamide fiber cord and one aliphatic polyamide fiber cord twisted therein. A total fineness of the composite fiber cords is from 1800 to 3200 dtex and an elongation under a load of 2.0 cN/dtex is from 3.0 to 4.0%. A rubber composition constituting the tread rubber is formed by compounding from 10 to 110 parts by weight of a silica having a nitrogen adsorption specific surface area of not less than 100 m2/g with 100 parts by weight of a diene rubber. A loss compliance of the rubber composition at 60° C. is not greater than 45 Pa−1.

摘要： A pneumatic tire includes a tread portion, sidewall portions, bead portions, and has at least one carcass layer disposed between the pair of bead portions. The ratio SW/OD between the total tire width SW and the tire external diameter OD satisfies the relationship SW/OD≦0.3. A first region A is defined between a pair of first boundary lines (L1, L1), second regions B are defined between a first boundary line (L1) and a second boundary line (L2), and third regions C are defined on the bead toe side of the second boundary lines (L2). Defining SA, SB, and SC as the cross-sectional area (mm2) of the first region A to the third region C, and defining the peripheral lengths (mm) of the first region A to third region C along the tire inner surface as a, b, and c, respectively, the relationship 7.5≦SA/a≦11.5 is satisfied.

Working reinforcement (2) comprises two working bi-plies (21, 22) radially superposed with respective axial widths (L1, L2), from first axial end (I1, I2) to second axial end (I′1, I′2). Each working bi-ply (21, 22) comprises two working layers (211, 212; 221, 222) radially superposed and respectively made up of axially juxtaposed portions of strip (5) of axial width W extending circumferentially in periodic curve (6) that forms, in the equatorial plane (XZ) of the tire and with the circumferential direction (XX′) of the tire, a non-zero angle A and has a radius of curvature R at its extrema (7). The difference DL between the respective axial widths (L1, L2) of the radially superposed working bi-plies (21, 22) is at least equal to 2×(W+(R−W/2)−(1−cos A)).
