A barrier layer is provided for an inflatable article for impeding the flow of inflation gas through the inflatable article. The barrier layer may be constructed of a material that is based upon a cross-linkable rubber composition, the cross-linkable rubber composition comprising, per 100 parts by weight of rubber (phr), between 1 phr and 40 phr of a chlorosulfonated polyethylene rubber, between 60 phr and 99 phr of a butyl rubber and a sulfur curing system.

Vehicle systems and components are set forth, which aim to reduce rolling friction caused in part by the contact between the vehicle's tires and the ground surface over which the vehicle is traversing. These systems and/or components thereof may increase the overall fuel efficiency of a vehicle. In the examples provided, the systems and/or components change the tread contact patch of one or more tires during movement of the vehicle.

The present invention relates to an explosion-proof tire, comprising a safety airbag, trigger sensors and a safety switch, wherein the safety airbag is arranged between a tire and a hub; the hub is provided with grooves; trigger devices of the safety airbag are arranged in the grooves; one end of each trigger sensor sticks into the tire; and the other end thereof is connected with a trigger device. The safety switch is arranged on the valve stem of the tire; and positive and negative electrodes on the valve stem are each connected with a trigger device. The safety switch disclosed by the present invention ensures that the safety airbag will not be triggered accidentally, and when a vehicle tire bursts, the safety airbag provided can instantly provide enough support force to ensure traffic safety.

A tire includes a tire body, a sealing film fastened to two side edge portions of the tire body and defining a gas chamber with the tire body, and a nozzle including an inserting member and an exterior screw member. The inserting member has an inner stopping portion disposed on an inner surface of the sealing film, a screw rod extended from the inner stopping portion and through the sealing film, and a gas-charging channel passing through the inner stopping portion and the screw rod and communicating with the gas chamber. The exterior screw member is screwed onto the screw rod and directly or indirectly urged against an outer surface of the sealing film.

Tire assembly for a bicycle rim, including a wheel tire with a tread surface and two tire beads, an inner tire disposed within the wheel tire, a tube disposed within the inner tire, and a valve arrangement for filling the tube and an intermediate space between the rim and the wheel tire with different air pressures. The inner tire in the filled and mounted condition bears on the tire beads of the wheel tire and presses the beads against the rim. The inner tire has a first through opening which in the mounted condition communicates with the intermediate space, and an insert part disposed between the rim and the tube and between the tube and the inner tire. The insert part forms an air duct between the rim and the tube and between the tube and the inner tire up to the through opening in the inner tire.

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.
