In a pneumatic tire including an annular tread portion extending in a tire circumferential direction, a pair of sidewall portions disposed on both sides of the tread portion, and a pair of bead portions disposed on an inner side of the sidewall portions in a tire radial direction, a load support body is disposed extending along the tire circumferential direction on an inner side of each of the sidewall portions, and the load support body is removably mounted to an inner surface of the sidewall portion via a mechanical engagement device.

The present invention relates to a hybrid run-flat having a buffering structure for a military vehicle, and more particularly, to a hybrid run-flat having a buffering structure for a military vehicle wherein a buffer member famed of a material different from the run-flat is provided on an outer circumferential surface of the run-flat of the military vehicle to enable a driving due to the buffer member even when a tire punctures, in which a groove for a lubricant is formed on an outer circumferential surface of the buffer member, and a buffer space as an empty space is famed therein, so that the impact relief effect is increased.

The wheel includes a tire, a rim, two groups of supporting members. The tire is coupled to the rim. The groups of supporting members are oppositely positioned and received in the tire. Each group of supporting members are separately positioned from each other. The supporting members of each group are coupled to an inner surface of the tire by injection method. Central axes of the supporting members of each group are coincident or parallel. A central axis of each supporting member is coincident with or parallel to a central axis of a central axis of the tire.

A puncture-proof structure for tires provides a spare tire body that can be installed to a tire rapidly and is applicable to various tire types by using fine tuning. The tire has its two top inner edges formed with circular hooked portions for engaging with the spare tire body made of serially connected combining blocks. When the tire gets punctured and damaged by a knife or a sharp article, the spare tire body allows the tire to keep work safely. Therein, the spare tire body is a C-shaped member composed of two C-shaped holding pieces. It can be engaged with the hooked portions of the tire rapidly and arm the tire with puncture-proof ability.

A tire with puncture-proof spare tire structure is provided. The structure forms a spare tire assembly that can be assembled rapidly and adapted to various tire types by being finely tuned. A tire using the spare tire structure is puncture-proof such that when punctured by sharp articles or knifes, the tire can still work to make safe arrival at a nearby repair workshop. This saves a car driver who has a damaged tire from the trouble of shoving the car and from the danger of endangering his/her life, in turn ensuring the public traffic safety.

A run-flat device is disclosed. The run-flat device comprises: a ring configured to be mounted against a wheel rim of a vehicle, the ring comprising a slot extending across its width and a radially outer boss; sectors each comprising a groove configured to cooperate with the boss, a first lateral edge having an angular extent defining that of the sector, and a second lateral edge having an angular extent less than that of the first edge, so that, with the sectors mounted on the ring, the second lateral edges define openings; an elastic band configured to be mounted around the sectors; and locking means, each configured to be inserted into one of the openings to hold the sectors together, and comprising a lateral flange extending from the second lateral edge.

The present invention provides a puncture-proof and run-flat tire with a spare tire that could be rapidly assembled and be adaptive to an tire body by finely adjusted and locked, thereby providing puncture-proof and run-flat function. The puncture-proof and run-flat tire includes an tire body having two protruding hooks on two inner edges on two sides of an inner ring of the tire body and a spare tire tightly engaged with one of the two protruding hooks of the tire body. Therefore, a vehicle could continue travelling safely if the tire body becomes flat due to damage caused by foreign objects. The spare tire includes a plurality of spare tire blocks assembled with an elastic ring, a first fine-adjustment wire, and a second fine-adjustment wire. Therefore, the spare tire could be rapidly mounted on the protruding hooks of the tire body to form the puncture-proof and run-flat tire.
