A dual, internal, pneumatic, boltless beadlock assembly for effectively securing a tire to a rim is disclosed. A pneumatic beadlock assembly is disposed inside a tire and mounted on a rim. A pneumatic beadlock assembly exerts a force on the two circumferential inner beads of a tire such that the tire stays in secure contact with the rim, even when the inflation pressure of the tire is not sufficient to lock the tire to the rim.

Embodiments of the present disclosure disclose a tire, a wheel and a vehicle, the tire includes an inner tube, a tire casing and a lubricating layer; the inner tube is a pneumatic tire, the tire casing is defined with an inner cavity, the inner tube is provided in the inner cavity, and the lubricating layer is provided between the inner tube and the tire casing. The lubricating layer is provided between two surfaces where the inner tube and the tire casing of the tire are in contact with each other, so as to reduce friction force caused by relative sliding between the inner tube and the tire casing slide when the tire pressure is zero or insufficient, avoid the inner tube from being worn out and then causing the air leakage, and improve the driving safety of the vehicle.

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.

An inner tube having a disconnected pattern, two ends of the inner tube having the disconnected pattern is respectively disposed with a first joint and a second joint. Free ends of the first joint and the second joint are respectively disposed with a first closed surface and a second closed surface; a sleeve further extends from a free end of the first joint or the second joint in a length direction of an inner tube body; the first joint and the second joint are connected face-to-face by the sleeve to enable the inner tube body having an elongated shape to be spliced to define an inner tube linked end-to-end. A tire, which uses the inner tube having the disconnected pattern.

The present disclosure relates to a light-weight tire inner tube comprising a film tube with a wall thickness of 100 to 400 microns, pneumatic tires containing the light-weight tire inner tube, and related methods for manufacturing the light-weight tire inner tube. The film tube is comprised of a film material comprising at least one thermoplastic engineering resin and optionally at least one saturated elastomer, and the film material of the film tube has an oxygen permeability of 8-15 cm.sup.3 O.sub.2/m.sup.2.Math.per day at 25 C.
