A puncture resistant liner assembly for use with a tire having a tread layer and opposed inside and outside walls extending away from the tread layer so as to define an interior tire space includes a primary protection layer that includes a plurality of primary pockets each having an outer wall defining a primary interior area and having a primary air capsule situated in the primary interior area. An auxiliary protection layer includes a plurality of auxiliary pockets each having a continuous outer wall defining an auxiliary interior area and having an auxiliary air capsule situated in the auxiliary interior area. Similarly, the liner assembly includes inner and outer protection layers adjacent and operably coupled to an inside and outside ends of the primary protection layer and that include a plurality of inner and outer pockets, respectively, each having a continuous outer wall defining an inner and outer interior areas.

This disclosure relates to a wheel assembly (1) comprising a wheel, the wheel having a hub and a rim concentrically mounted to the hub, a plurality of deformable chambers (6) disposed outwardly of the rim, each chamber extending about a discreet portion of the wheel and containing a transition substance (15), and an actuator (14) configured to transform the transition substance (15) within each chamber (6) between a fluid state in which the deformable chamber (6) can deform into a conformal state as the wheel encounters an obstacle during use, and a rigid state in which the transition substance is rigidified to maintain the deformable chamber (6) in said conformal state to provide increased purchase on said obstacle.

This disclosure relates to a wheel assembly (1) comprising a wheel, a deformable chamber (6) containing a transition substance (15) comprising jamming particles and an interstitial gas, and an actuator (14) configured to transform the transition substance (15) between a fluid state in which the deformable chamber (6) can deform into a conformal state as the wheel encounters an obstacle during use, and a rigid state by evacuation of the interstitial gas in which the transition substance is rigidified to maintain the deformable chamber (6) in said conformal state to provide increased purchase on said obstacle.

A multiple chamber pneumatic tire having an upper section and a lower section. A diaphragm separates the upper section from the lower section. The lower section has at least two chambers. The chambers each have a chamber valve, a nail guard layer, a plurality of fibers having an end connected to an inner wall surface of a chamber, and an interconnected barrier connected to at least two portions of a chamber wall surface. The upper section of the tire has at least one linkage located within at least one tube with a primary end connected to a chamber valve of a chamber and a secondary end connected to a tire rim or to a main valve. A tire pressure monitoring system can be in communication with a chamber valve. The tire can have a ring with at least one retractable stud.

A self-sealing pneumatic tire having at least one cohesive sandwich radially inward of the pneumatic tire is provided. The at least cohesive sandwich may include a cohesive material under pressure, facilitating a recovery capacity upon being pierced by a sharp object, whereby the molecules of the cohesive material cohesively reattach, self-sealing any passageway or space created by the sharp object. The self-sealing pneumatic tire may also provide a loculated-diamond-section layer located radially inward of the outer cohesive sandwich, further supporting the self-sealing pneumatic tire. The external rubber tread are disposed along the circumference of the tire in some embodiments can be separate from the surface of the tire yet secured in place by attachments. Once fully utilized, this external rubber tread can be replaced by a new version without having to replace the entire tire.
