The present invention is directed at a tire design, which allows for proper operational characteristics in all operating conditions, and is not dependent on pneumatic pressurization. The tire is mounted in a wheel rim, and comprises an integral homogeneous toroidal body having a pair of spaced-apart radially extending sidewalls and a cross member. Each sidewall has a first and a second end and an internal face and an external face, with the second end of each of the sidewalls integrally merging into the cross member. A set of rim-engaging surfaces at the first end of each of the sidewalls allows effective mounting to conventional tire rims. An annular chamber is defined by the internal faces of the sidewalls and an internal top wall on the cross member opposite the at least one road engaging surface. The set of rim-engaging surfaces includes a lobe-like portion at the first end of each of the sidewalls, the respective lobe-like projections may be separable when the tire is not mounted on the rim, but being compressed into engagement when the tire is mounted in the rim, thereby closing the annular chamber, or integral with one another to form the enclosed chamber.

The present invention addresses the problem of providing a novel tire / wheel assembly. The tire / wheel assembly has: a wheel coupled to a rotating shaft; an elastic tube arranged on the outside of the wheel in the radial direction and having air filled therein; a rigid protection ring arranged on the outside of the tube in the radial direction, separated from the wheel; and a tread ring arranged on the outside of the protection ring in the radial direction and such that the inner circumferential surface thereof is in contact with the outer circumferential surface of the protection ring.

This tire has: a tire frame that is annular and is formed from a resin material; and a reinforcing metal cord member that is wound to the outer periphery of the tire frame. At least a portion of the reinforcing metal cord member is covered by a covering mixture containing at least a thermoplastic resin and a specific elastomer selected from the group consisting of the belowmentioned (1) to (3): (1) a polyurethane thermoplastic elastomer; (2) a polystyrene thermoplastic elastomer; and (3) an olefin thermoplastic elastomer containing at least one selected from the group consisting of an acid-modified olefin thermoplastic elastomer having a modulus of elasticity of less than 140 MPa and an acid-unmodified olefin thermoplastic elastomer having a modulus of elasticity of less than 140 MPa.

A tire includes a ring shaped tire case formed from a resin material, a reinforcement cord having a higher rigidity that that of the resin material, wound in a spiral shape on the outer peripheral section of the tire case and having at least a portion of the reinforcement cord embedded in and making close contact with the outer peripheral section of the tire case when viewed in a cross-section along the axial direction of the tire case and a tread provided on the radial direction outside of a reinforcement cord layer formed by the reinforcement cord.

The present invention provides a tire configured by joining together tire forming members consisting of a thermoplastic material, wherein the joined sections have sufficient strength. A molten thermoplastic material (43) for welding is extruded toward the portions to be joined of two half tire bodies (17A) which are butted against each other face to face and consist of a first thermoplastic material, and one half tire body (17A) and the other half tire body (17A) are welded together by the thermoplastic material (43) for welding. The half tire bodies (17A) are welded together without melting the half tire bodies (17A), and as a result, the thermoplastic material which forms the half tire bodies (17A) is prevented from degrading and the joined portions have sufficient strength.

This invention pertains to a new method for manufacturing tires, an apparatus used with the new method and the article manufactured by the new method. The article is called the reinforced liquid elastomer tire (RLET). The method of manufacture includes placement of reinforcing materials inside a tire molding cavity and subsequently surrounding the reinforcement with a liquid elastomer which encapsulates the reinforcement and takes the outside shape of the tire mold. The liquid elastomer is solidified and the completed RLET is removed from the mold and ready for service.

To easily manufacture a tire the color of which does not fade due to traveling, a tire case (17) which is a tire (10) structural member is formed by injection molding using a colored first thermoplastic material which contains a pigment. A tire the color of which does not fade due to traveling can be easily manufactured.

An elastomeric tire with arch shaped shoulders for mounting onto a rim that is manufactured by spin casting or molding methods that includes an annular cavity that is centered under the tire tread having equal thicknesses of side walls and an area under the tread whose slope outwardly into shoulder that the side walls upper ends intersect that have greater thickness and which side walls lower ends include beads that are each spaced a selected distance from the surfaces of the side wall ends that slope upwardly from inner to outer surfaces and with the tire preferably including plies that extend across the tire having ends that wrap around the beads and belts fitted around the tire circumference, above the plies, and including porous spacers fitted between the layers of plies and belts to pass a flow of the elastomeric material therethrough during tire formation.

The invention relates to a steel rib tire, which overcomes the defects of easy pricking leak, easy tire burst, requirement of reaeration, non gunslinging resistance, complicated processing and high cost of the prior vehicle tires. The steel rib tire is characterized in that one end of a steel plate 3 is connected with a steel sheet ring 2, while the other end is connected to the inside of a tire ring 4; both ends of an annular hook slot ring 5 are connected to the inside of the tire ring 4 respectively; an annular rubber air holding ring 6 is connected to the inside of the annular hook slot ring 5; a pressing ring 7 is connected to the inside of the annular rubber air holding ring 6; and an inflating nozzle 8 is connected to the annular rubber air holding ring 6. The steel rib tire is arranged on the wheel rim of a vehicle, and can be used after being inflated with standard air pressure through the inflating nozzle 8. The steel rib tire has gunslinging resistance, and the problems of tire burst and pricking leak do not exist, so that the steel rib tire achieves no tire patching and tire pasting truly, and overcomes the defects of complicated processing, high cost, easy pricking, easy tire burst and gunslinging fear of the rubber tire. The steel rib tire fills a blank of the tire manufacturing industry, and provides reliable and safe technology for the safe running of the vehicles. The technology fills the blank of the prior art, and is suitable for processing the steel rib tires.

A tire includes: a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections, a pair of side sections, and a crown section; a ring shaped bead core that is embedded in and joined to each of the bead sections, and that is formed by a single strand, or plurality of strands, of bead cord extending in the tire circumferential direction, and covered with, and joined to, a covering resin material; and an extension portion that extends from each of the bead cores in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member.

This pneumatic tire makes it possible to improve production efficiency while ensuring engagement with a rim, and to increase material recyclability. A pair of bead parts 5 are each configured by an annular bead core 10 comprising a thermoplastic resin, and a bead core coating part 20 comprising a thermoplastic resin.
