摘要： PURPOSE:To improve the sealing performance in the fitting surface, in the retreading of a tubeless tire for a bus or the like, by forming a cut-out surface at the bead toe part, and by fitting a reinforcement, which is made of rubber and in which the ratio of the length between the inner end in the axial direction of the tire and the bead heel end to the length of the base surface before cut-out is specific, to the cut-out part. CONSTITUTION:In the base body 5 of a retreaded tire, a cut-out surface 4 is formed in the bead toe part 3, and thereto a rubber-made reinforcement 9 having an extended surface 7 continued to the base surface 6 of a bead part 2 is fitted. The distance l1 from the inner end 8 of the reinforcement 9 in the axial direction of the tire to the heel end 12 of the bead part is set to be greater than 1.0 time and less than 1.3 times the length l2 of the base surface 6 before cut- out. By this constitution, air leakage from the fitting parts can be prevented, enabling the retreading of the tubeless tire.

摘要： PURPOSE:To respectively improve engagement property at the time of rim assembly and fitness after the rim assembly by forming a rubber chafer in the periphery of a bead part with an outside soft rubber layer and an inside hard rubber layer. CONSTITUTION:A rubber chafer 5 is arranged in a tire so that an inner liner layer 4 is covered along the periphery of a bead core 2. In this case, the rubber chafer 5 is formed with a laminated body made of an inside hard rubber layer 5H and an outside soft rubber layer 5S. The soft rubber layer 5S is formed with a rubber of JIS hardness Hs 50-65, complex elasticity rate E of more than 3.0MPa and compression set of less than 25%. Additionally, the hard rubber layer 5H is formed with a rubber of JIS hardness Hs 70-85, complex elasticity rate E of more than 6.0MPa and compression set of less than 32%. Consequently, engagement property at the time of rim assembly and fitness after the rim assembly are respectively improved.

摘要： PURPOSE: To facilitate assembly by forming a contact surface on the side facing the beads of a rim horn so as to be inclined outwards by a prescribed angle to radial direction, thereby keeping seating pressure safety. CONSTITUTION: A contact surface 9 facing the beads 2 of a rim horn 3 is formed so as to be inclined by an angle α between 5 deg. and 50 deg. outwards to the radial direction 10. A rim seating surface 11 for the tire beads 2 following the rim horn 3 inwards in the axial direction is inclined in the same way, and is formed so as to have minimum diameter inward in the axial direction. The maximum diameter in the range of the rim seating surface 11 is positioned outward in the axial direction, and an inclination angle β to the axial direction is set between 10 deg. and 40 deg.. An accident traveling supporting surface 12 is formed outward in the radial direction from the rim seating surface 11, and in the central range of a rim 1, a drop base 13 is formed. It is thus possible to conduct assembly wish seating pressure safety kept.

摘要： PURPOSE: To improve bending ability by a method wherein a cable form rigid substance of which a bead core, embedded in the bead of a tire, consists is provided with a surface to block adhesion to vulcanized rubber and rigid substances of an outside core layer are disposed to prevent from contact with each other. CONSTITUTION: In a vehicle pneumatic tire 1, a bead 2 provided at an internal part with a bead core 3 consisting of a rigid substance 4 formed of a steel wire is disposed in a manner to surround the rim flange 7 of a rim 8 from the inside and the periphery of the bear core 3 of the bead 2 is wound with a radial carcass 10. In this case, the bead core 3 consists of cores 4 and 1; six wires 4 and 2 of a small diameter inside layer; and sin wire 4 and 3 of an outside layer. The wires 4 and 2 of the inside layer are formed slightly further slender than the wires 4 and 3 of the outside layer and a wide space 9 is formed between the wires 4 and 3 of the outside layer. Further, bead rubber is engaged in a knurling state with the space 9.

摘要： PURPOSE:To allow a car to run safely even while in running leaving a tire flat by providing a rim with a projection supporting the tire in flat and forming the tire with a hollow toroidal carcass along the projection. CONSTITUTION:A rim 3 is provided with a projection 6 between rim seat sections 5 and 5. A tire 2 has bead sections 7 and 7, side wall sections 9 and 9, a tread section 10 and a bridge section 11 forming a hollow toroidal tire base body 12 by coupling members to each other. In addition, the bridge section 11 is provided with a ring like protrusion 13 meeting to the projection 6 of the rim 3. This relieves the shock in car running with a tire being flat. Moreover, because a carcass is formed in a toroidal shape, the compressive strain acting on the carcass is substantially reduced even in car running with a tire being flat resulting in the prevention of the carcass from being damaged.
