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.

A motor vehicle tire is disclosed with a pair of post-cure run-flat inserts, each of the pair of post-cure run-flat inserts is disposed within a tire cavity between a shoulder region and a respective upper sidewall region of the tire. The tire further includes a cylindrical sidewall defining an interior cylindrical cavity, each of the cylindrical sidewall and the interior cylindrical cavity extending 360 degrees about a rotational axis of the tire, the cylindrical sidewall having an exterior surface contacting a radially inner surface of an inner liner between the shoulder region and the respective upper sidewall region during a normal inflation condition of the tire.

A spare tire assembly for pre-installation in tires to protect tires when flattened includes an insert that is resilient. The insert is toroidally shaped and defines a central opening. The central opening is complementary to a rim of a wheel, such that the insert is positionable between the rim and a tire that is to be coupled to the rim. A cover is positioned over an outer surface of the insert. The cover is configured to shield the insert from potential damage as the wheel rotates with the tire in a deflated condition. A user is able to operate a vehicle having a flattened tire that is configured with the insert for a period of time without damaging the flattened tire.

A tire-wheel assembly includes a run-flat support member that is provided with a support surface formed on an outer circumferential side, and that is disposed on a rim in a cavity portion of a pneumatic tire, the run-flat support member being formed by connecting a plurality of foamed bodies in a tire circumferential direction with a band-like member, and being disposed in an annular shape on an outer circumference of the rim.

Disclosed is a combination flat-proof tire and low friction insert having particular application for use on a motorcycle. The insert is preferably manufactured from a resilient (e.g., closed cell foam) material. The insert fills the tire and is movable relative thereto. A low friction sleeve surrounds the insert so as to reduce both friction and heat at the interface of the insert and the tire to minimize the degradation and replacement of the insert. By way of example, the low friction sleeve is manufactured from a smooth textile material having a thickness of about 0.005 inches. In one embodiment, the insert is separated into a plurality of compressible segments aligned side-by-side one another around the tire. Relatively hard spacers are located between adjacent pairs of the insert segments to apply compressive forces to the insert segments in response to road conditions.

A module, usable with a plurality of other modules, to obtain an annular modular assembly adapted to fill a tire of a cycle or motorcycle. The module can be removably inserted into the tire and includes a body made of foamed elastomeric material defining a portion of the annular modular assembly. The body has a shape of circular or ellipsoidal section with tapered end areas designed, in use, to remain facing or in contact with one of the tapered end areas of the adjacent modules. The tapered end areas define respective planes converging toward the center of the tire and angularly spaced by an angle between 8? and 30?.

A run flat device configured to be fitted to a tubeless mounted assembly for a motor vehicle, which includes a wheel rim and a tire cover including beads mounted against edges of the rim, the run flat device including: an annular supporting structure which is configured to be mounted around the rim so as to support the cover following a drop in inflating pressure inside the mounted assembly, including: three composite spring segments forming sectors in an arc of a circle assembled circumferentially around the rim forming the annular supporting structure by means of transverse pins whose shape geometry is asymmetrical; and an arrangement for locking the beads against the edges which are configured to connect the annular supporting structure to these beads.

An enhanced static runflat system is disclosed. According to an exemplary embodiment of the present invention, at least one predefined structural stopper provided on the outer peripheral surface of the cylindrical section of the wheel rim, whereby at least one predefined structural stopper secures, an inner circumference of the annular static runflat to an outer circumference of the wheel for arresting a movement of the static runflat over the wheel rim.
