摘要： PROBLEM TO BE SOLVED: To provide a pneumatic tire, especially a run-flat tire, which is excellent in stable traveling under the deflated condition and in bead-part durability. SOLUTION: In order to form a wheel with a tire, a reinforcing rubber 3 is arranged on the internal surface of tire 1, while the tire 1 is fitted to an application rim 4. In this case, a bed reinforcing part 8, which projects toward the outside in the lateral direction 7 of the tire 1, is installed in the position at which a bead part 6 of the tire 1 and the upper part (5a) of the rim flange stand opposite to each other. In addition, a rim-slippage preventing layer 9, which has a facing surface whose redius of curvature is substantially equal to that of the upper part (5a) of the rim flange and which consists of relatively soft rubber, is provided at a position where the bead reinforcing part 8 and the upper part (5a) of the rim flange stand opposite to each other. Moreover, the rim-slippage preventing layer 9 of the bead reinforcing part 8 becomes in tight contact with the upper part (5a) of the rim flange under such conditions as; (l) a range of air pressure from the atmospheric pressure to the air pressure less than 80% of that corresponding to the maximum load capacity and as (2) a load condition from the no load condition to the maximum load condition.

摘要： PROBLEM TO BE SOLVED: To provide a tire for an ATV maintaining a flexible tire characteristic and having an excellent run flat characteristic without requiring a special rim. SOLUTION: A carcass 30 extended toward a circular bead core 26 and surrounding the periphery of the bead core 26 is provided on the inside in the radial direction of a circular tread 12. An elastomer apex 48 is extended to the outside in the radial direction from the bead core 26 in adjacent to the bead core 26. An elastomer insert 42 is extended to the inside in the radial direction and the axial direction of the outside portion in the radial direction of the apex 48 toward the bead core 26 to the inside in the radial direction from the edge of the tread 12.

摘要： PURPOSE:To improve the safety in case of the puncture of a tyre by specifying the aspect ratio and the height of a tread edge, making the tread width bigger than the maximum width of a carcass and setting up a carcass shape from the maximum width position to a bead part specifically. CONSTITUTION:A tyre aspect ratio is set up below 80% and the edge height hd of a tread part 5 to 50-100% of the height HC of a carcass cross section and a tread width WT bigger than the carcass maximum width WT to a bead core 2 is formed with a projecting arc part B1 having its center staring inside the tyre and having a curvature radius R1 and with a recessed arc part B2 having its center staying outside the tyre and having a curvature radius R2. At this time, the curvature radius R1 is set up smaller than R2 and the ratio R1/R2 bigger than 0.5 and smaller than 1.0. By this composition, safe running to a repair shop can be performed even if the tyre puncture.

摘要： PURPOSE:To improve the extent of durability, by disposing a crescent reinforced tubber layer as in the specified structure by a high elastic rubber layer and a crack resisting rubber layer of specified performance each, in case of the above-captioned tire for run-flat running of the specified compression. CONSTITUTION:A crescent reinforced rubber layer G is constituted of a high elastic rubber layer G1 of 70-85 deg. in Shore A hardness and 25-60kg/cm in 100% expansion modulus, disposed at the side of a carcass layer 40 making the central part of a sidewall part 20 as the main body, and a crack resisting rubber layer G2 of 55-70 deg. in Shore A hardness and 10-30kg/cm in 100% expansion modulus, situated in a shoulder part 70 at an upper part of the sidewall part 20 and being partially superposed at the inside in the tire axial direction of the said high elastic rubber layer G1. And, the ratio G1/G2 of each of each sectional area of these rubber layers G1 and G2 should be set to 1
