A run-flat tire and method of manufacturing is disclosed with a pair of post-cure sidewall-stabilizing run-flat inserts. Each of the pair of post-cure sidewall-stabilizing run-flat inserts extends circumferentially about a rotational axis of a tire; includes a first terminating end, and a second terminating end, opposite the first terminating end; and is disposed on a radially inner surface of a sidewall of a tire such that the first terminating end terminates above the bead core and the second terminating end terminates along at least one of the sidewall and a respective adjacent shoulder.

A tire-wheel assembly includes a run-flat support member disposed on a rim within a cavity portion of a pneumatic tire and including a support surface formed on an outer circumference; the run-flat support member being a bladder comprising a foamed body therein and being disposed in an annular manner around an outer circumference of the rim.

The present technology provides a pneumatic tire having a mechanical fastener member for attaching an object with specific functionality to an inner surface of the pneumatic tire, particularly, a pneumatic tire such that, as the pneumatic tire rolls, the object with the specific function attached by the mechanical fastener member can be effectively prevented from executing rotating motion about the mechanical fastener member as a rotation central axis. The pneumatic tire of the present technology has a first member of a mechanical fastener separable into two members, disposed on the tire inner surface. On the tire inner surface around the mechanical fastener member, a recessed flat surface region is formed as a recessed portion having a step from peripheral portions of the recessed portion.

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.

This invention relates to a tyre insert comprising an inner component comprising a first foam material, and an outer component comprising a second foam material, wherein the second foam material has either a higher or lower density than the first foam material, and wherein the outer component comprises an inwardly facing channel which is shaped to accept the inner component. This invention also relates to a wheel for a vehicle comprising a tyre insert as described above, as well as to a vehicle comprising the wheel.

A run-flat tire insert, according to particular embodiments, that is configured to be received inside a cavity of a tire. The run-flat tire insert comprising a monolithic, generally toroid shaped insert that includes (a) a first and a second sidewall, (ii) an outer surface that couples the first sidewall to the second sidewall, and (iii) an inner surface that couples the first sidewall to the second sidewall. Additionally, the monolithic, generally toroid shaped insert has an outer diameter that is substantially equal to an outer diameter of a tire in which the monolithic, generally toroid shaped insert will be installed into when the tire is not inflated with air.
