Pneumatic tyre (1) comprising a carcass ply (11), two ring beads (12), a tread strip (10), a tread belt (15) comprising at least two tread plies (16), an innerliner (2) and an additional functional material layer (4,5) arranged between the innerliner (2) and the inner cavity (17) of the pneumatic tyre (1), wherein between the innerliner (2) and the layer of additional functional material (4,5) a net layer (3) is interposed, which facilitates the removal thereof during disposal at the end-of-life of the pneumatic tyre.

A balanced non-deflatable vehicle tire providing balanced operation even after partial puncture, adjustment of overall air pressure, use of standard rimmed wheels, and the option of being retrofit into existing tires, by providing alternating layers of puncture-resistant sheet material and pressurized-cell sheets, and an inner-tube to fill the remaining internal space and to adjust and apply balanced pressure internally.

A self-healing pneumatic tire, which uses the sealant stored in the tire to fix a leak, is disclosed.

There is provided a piece for a modular tyre liner, the piece being planar and generally rectangular and cut to define: a key head and a key hole, the key head configured for insertion into an associated key hole of an adjacent piece for engagement in use to form a mechanical interlock with the adjacent piece and wherein the key head and a key hole are configured for allowing movement of the piece with respect to the adjacent piece along the length of the liner in use.

A vehicle wheel includes a rim, an inflatable tire, a grounding tire, and a safety unit. The rim includes two tire engagement portions spaced from each other in a longitudinal direction. The inflatable tire is mounted around the rim and includes an inner annular bottom wall and two inner annular sidewalls respectively on left and right sides of the inner annular bottom wall. Each inner annular sidewall includes an inner side having a lip pressing against one of the tire engagement portions of the rim. The grounding tire is mounted around the inflatable tire and includes an outer annular bottom wall capable of rolling contact with the ground. The safety unit is sandwiched between the inflatable tire and the grounding tire to couple the inflatable tire and the grounding tire together, permitting synchronously rotation of the inflatable tire and the grounding tire while increasing the anti-slipping effect.

A self-repairing inflatable article including an inflatable component that includes an interior surface and an exterior surface, a sealed flexible package adjacent to the inflatable component, and a sealant composition disposed in the sealed flexible package. The sealed flexible package is configured to release the sealant composition upon puncture, tearing or other breach of the inflatable component.

A tire-wheel assembly comprises a wheel coupled to a rotating shaft; an elastic tube disposed on an outer side of the wheel with respect to a radial direction, the interior of the tube being filled with air; a rigid protective ring disposed on an outer side of the tube with respect to the radial direction separated from the wheel; and a tread ring disposed on an outer side of the protective ring with respect to the radial direction, an inner circumferential surface of the tread ring contacting an outer circumferential surface of the protective ring.

The present disclosure describes a self-repairing article comprising an inflatable component comprising one or more material layers wherein at least one material layer comprises an elastomer. It also describes a self-repairing article comprising a sealed flexible package disposed within or between material layers of the inflatable component, and a repair composition disposed in the sealed flexible package, wherein the sealed flexible package comprises a metal foil and is configured to release the repair composition upon puncture of the inflatable component.

A ballistic resilient run-flat tire device, kit and method for manufacturing the same are presented for providing a vehicle a capability of traveling for at least 30 miles at 30 miles per hour, after the device has been compromised as of result of exposure due to ballistic ordinance rifle shots such as 7.6239 mm and 7.6254R or air loss from road hazard punctures. The device includes a tire carcass and a polyurethane inner coating inside the tire carcass that defines an inflatable hollow chamber within the ballistic resilient run-flat tire. The tire carcass has an annular tread, sidewalls, and beads. The polyurethane inner coating inside the tire carcass defining a hollow chamber provides additional protection along the sidewalls and tread of the tire carcass. The kit includes the un-interconnected elements of the device. The method includes the steps of curing, discharging, filling, injecting, introducing, mounting, obtaining, and preparing.

A pneumatic vehicle tire is provided. The tire includes a thread, an inner surface lying opposite the thread, a self-sealing sealant and a sound-absorbing open-cell foam ring arranged inside the pneumatic vehicle tire. The foam ring is adhesively attached to the inner surface and adheres to the self-sealing sealant which is applied before the sound-absorbing open-cell foam ring is attached to the inner surface. The self-sealing sealant has, at least immediately after being applied, a tackiness required for an adhesive attachment of the sound-absorbing open-cell foam ring. A closed-cell material ring is arranged between the sound-absorbing foam ring and the self-sealing sealant to prevent a diffusion of the sealant into the open-cell foam ring. The closed-cell material ring effects an airtight condition.
