摘要： A pneumatic tire has no spew or no spew trace on a sidewall surface of the pneumatic tire and reduces air resistance. The tire includes a plurality of dimple-like recesses and a plurality of linear valley portions. The dimple-like recesses (16) are provided in a first region (R 1 ) including a tire maximum width position of the sidewall surface of the tire. The linear valley portions which are formed by serration of the sidewall surface, extend linearly in one direction in the first region (R 1 ) and provided around each of the recesses (16) so as to enclose each of the recesses. When a size of an occupied area of each of the recesses on the sidewall surface is represented by an equivalent diameter of a circle, an interval distance between the linear valley portions is smaller than the equivalent diameter.

摘要： A pneumatic tire, in which one of hydroplaning resistance and wear resistance can at least be maintained while the other can be enhanced and rolling resistance can be reduced, includes, in a tread portion, a pair of circumferential main grooves (12,14) and a land portion (13) provided between the pair of circumferential main grooves (12,14) and extending in the tire circumferential direction. The land portion (13) includes a bulging portion (44) bulging in a second arc shape (R2)in a tire radial direction as a sectional outline of a tread surface of the land portion and chamfered portions (48,50) connected to the bulging portion (44) and extending straight toward respective groove walls of the circumferential main grooves (12,14). A portion of the bulging portion (44) bulges in the tire radial direction with respect to a virtual tread profile line (40) which is determined by a first arc shape (Rl) in a sectional shape of the tread portion. A maximum bulging amount (H) is 0.1 to 0.8 mm. The virtual tread profile line (40) extends across the chamfered portions.

摘要： A pneumatic tire includes a plurality of circumferential grooves (12,14,16) and a first land portion (22). The circumferential grooves extend continuously in a tire circumferential direction. The first land portion extends in the tire circumferential direction between a pattern end (18a) and one of the circumferential grooves (12) in a shoulder region (18) located outside the circumferential grooves (12,14,16) in a tire width direction. The first land portion (22) has a first lug grooves (23) extending from the pattern end (18a) in the tire width direction and closed without communicating with the circumferential grooves are arranged in the tire circumferential direction. At least one circumferential groove (12) is a wave shaped with a constant groove width (12W) in the tire width direction at a tread surface and formed in a wave -shape in the circumferential direction at the tread surface and groove bottom (12b) the wave -shaped circumferential direction at the tread surface and groove bottom (12b). The wave- shaped circumferential groove (12) has a shorter cycle length of waves (12P1) at the groove bottom than at the tread surface.

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.

摘要： A pneumatic radial tire having a structure where the lapel edge of the carcass is tucked under a belt layer and exhibiting high durability and steering stability can be easily produced using a carcass material of an existing size without preparing an ultra-wide carcass material. Two layers of carcasses (A, B) 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 essentially equal and the carcasses (A, B) are offset in opposite directions 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 made different, 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 and portion (6e) in the tire width direction and is terminated thereat.

摘要： At least two circumferential main grooves (61, 62) and three land portions (63, 64, 65) are formed in a tread portion of a pneumatic tire (1) on each side of a tire equatorial plane. In a cross section in a tire meridian direction of the pneumatic tire (1), profile lines of the land portions (63, 64, 65) form arcs, and extension lines of profile lines of adjacent land portions (63, 64, and 64, 65) intersect with inflection points (Pa, Pb) in the circumferential main grooves (61, 62). Tensile strength of a reinforcing layer (8) in areas of the land portions (63, 64, 65) is larger than that in an area of the circumferential main grooves (61, 62) having the inflection points (Pa, Pb).
