摘要： The present invention relates to a tire (1) comprising:
- a tire carcass (2) on which a tread (3) with two opposite shoulders (4, 5) is arranged;
- from each shoulder (4 or 5), a flank (6 or 7) extends, ending in a bead (8 or 9) adapted to cooperate with an external bead surface (10 or 11) thereof with an edge (12 or 13) of a channel (14) of a rim (15) of a wheel (100) of a vehicle;
- said tread (3) and said flanks (6, 7) embrace a main chamber (16) on three sides;
- each of said flanks (6 or 7) comprises an internal flank surface (17) ;
- said tire (1) further comprises at least one bead seat wall (19) which is connected to two attachment portions (20, 21), separate from each other, of the internal surface (17) of at least one of said flanks (6 or 7), forming a bead seat chamber (22) with said at least one flank (6 or 7);
- wherein one of said attachment portions (20) is placed close to the bead (10 or 11) at which said at least one flank (6 or 7) ends; and wherein
- said bead (10 or 11) placed close to said attachment portion (20) comprises a bead projection (23);
- said bead projection (23) protrudes from the opposite side of said external bead surface (8 or 9) into said main chamber (16);
- said bead projection (23) forms a bead resting surface (24) which is connected to said at least one flank (6 or 7) and faces said bead seat wall (19) so that when said tire (1) is statically and/or dynamically stressed by the rolling of the wheel (100) of a vehicle, it allows the support of said bead seat wall (19) on said bead resting surface (24) .

摘要： A multi air chamber tire 1 includes a tread portion 4, a pair of bead portions 2, a pair of sidewall portions 3 extending between the tread portion 4 and the pair of bead portions 2, and partition walls 30 respectively provided to half portions of a tire which are defined with respect to a tire equator plane, the partition walls 30 partitioning an inner cavity of the tire to form a plurality of air chambers disposed adjacent to each other. Each of the partition walls 30 includes a first coupling portion 9a coupled with a tire inner wall surface, and a second coupling portion 9b coupled with the tire inner wall surface at a position outward of the first coupling portion 9a in a tire radial direction. In a state where the tire 1 is filled with fluid, a first air chamber 20 is formed in a space located at a position inward of the partition walls 30 in a tire width direction, and a second air chamber 21 is formed in a space located between a partition wall of the partition walls 30 and the tire inner wall surface of a sidewall portion of the pair of sidewall portions 3.

摘要： A wheel provided with a tyre in tyre installation in which an outer ground engaging tyre is mounted on a rim of the wheel and an inner inflatable member is mounted on the rim inside the outer tyre. The inner surface of the outer tyre and the outer surface of the inner inflatable member are provided with respective electrically conductive members suitably in the form of induction loops. A controller determines when the respective electrically conductive members come into close proximity or contact, enabling manual or automated adjustment of air pressure to minimise abrasion between the outer tyre and inner inflatable member.

摘要： An air bladder 2 for a safety tire can be produced while maintaining the high productivity because a curve of tensile force to an elongation reaching to an elongation of 50% has a hook shape changing from a sharp linear form in the vicinity of an elongation of 5% to a generally flat curved form in a crown region 5 of an extended deformation portion 3 and an upward sloping shape smoothly increasing with the increase of the elongation in a side region 6 thereof, and the extended deformation portion does not contact with the inner face of the tire during the normal running of the tire and can equally close to the inner face of the tire during the run-flat running to efficiently support the load.

摘要： A safety tire with relatively even temperature distribution in the tire and an air bladder used for it are provided by smoothly flowing air filled in the tire over the entire tire inside in the air filled state even when an air bladder is housed in a tire.
A safety tire 1 is provided with a tire 2 and an air bladder 3 in the hollow toric shape. In the air-filled state, a cavity S 1 is formed between the outer surface 8 of the air bladder 3 and the inner surface 9 of the tire 2. In the runflat state, the air bladder 3 is inflated and deformed to take over load support from the tire 2. The air bladder 3 has a raised portion 12 on a specific outer surface area A so as to form a flow passage 13 through which air can flow between the rim and the air bladder. The raised portion 12 has on the side face a rigid reinforcing portion 15 whose width is gradually increased from the top face 14 side to the flow passage 13. The ratio of the flow passage 13 to the specific outer surface area A is in the range of 50 to 95% by area ratio.
