    C and the radiuses R
    S , R
    E and R
    T being in metres; each sidewall comprising an additional reinforcement (120) consisting of threadlike reinforcing elements having an elongation at break EB

    摘要： [Object] To provide a pneumatic tire 2 which is excellent in durability.
    [Solution] The tire 2 has a marking on each sidewall 8 thereof. A large number of dimples 62 are formed in a region between the marking and a rim protector 34. These dimples 62 are arranged along a circumferential direction. These dimples 62 form a row. The row includes:
    (1) dimples each having a plane shape of a circle; or
    (2) dimples in each of which a plane shape is substantially a rectangle, and a ratio of a length in the circumferential direction to a width in a radial direction is equal to or greater than 1.0 and equal to or less than 3.0.

    摘要： [Object] To provide a pneumatic tire 2 for which processing of a mold is easy and which is excellent in durability.
    [Solution] A tire 2 has a large number of dimples 62 on sidewalls 8 thereof. These dimples 62 are divided into dimples 62 of a first row I and dimples 62 of a second row II. The number of the dimples 62 per one row is 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 25, 30, 32, 36, 40, 48, 5060, 72, 75, 80, 90, 100, 120, 144, 150, 160, 180, 200, 225, 240, 300, 360, 375, 400, 450, 480, 500, 600, or 720. Preferably, the number of the dimples 62 of the second row II is equal to the number of the dimples 62 of the first row I.

    摘要： A pneumatic radial tire having a structure where the lapel edge of carcass is sandwiched between belt layers and exhibiting high durability and steering stability can be produced easily using a carcass material of an existing size without preparing an ultra-wide carcass material. Carcasses (A, B) of two layers are extended from a tread portion (1) to a bead portion (3) via right and left sidewall portions (2), and the opposite ends thereof are turned down from the inside of the tire to the outside around right and left bead cores (4, 4). A belt layer (6) is arranged on the outer circumferential side of the carcasses (A, B) and the overall width of the carcasses (A, B) in the tire width direction is substantially equalized and the carcasses (A, B) are offset reversely in the tire width direction. The turn back lengths from the right and left bead cores (4, 4) at the opposite ends of the carcasses (A, B) are differentiated, the carcass with shorter turn back length is terminated in the vicinity of the bead core (4), and the carcass of longer turn back length is extended to the inside of the belt layer end portion (6e) in the tire width direction and is terminated thereat.
