Abstract: Various embodiments of a tire, and other objects, having an aerodynamic and/or hydrodynamic surface treatment are disclosed.

Abstract: Tire assemblies are disclosed. In one embodiment a tire insert assembly includes an elastomeric tire insert constructed to be received within a tire, the tire having sidewalls and a tread portion. An upper crown surface of the tire insert and a lower surface of the tire define an outer chamber and the tire insert defines an inner chamber. The tire insert may be configured to support a substantial portion of the sidewall of the tire when the inner chamber is inflated.

Abstract: This invention relates to a rubber composition prepared with reinforcement comprised of a combination of precipitated silica aggregates and pelletized rubber reinforcing carbon black composites of carbon black and organic binder of a controlled hardness and to a tire with at least one component comprised of and derived from such rubber composition in which said carbon black pellet composites are disintegrated (fragmented) in situ within said rubber composition in the presence of particulate precipitated silica and silica coupling agent. In one aspect the invention relates to a tire having a component of a rubber composition comprised of at least one conjugated diene-based elastomer and reinforcing filler comprised of a combination of precipitated silica, silica coupling agent and fragmented rubber reinforcing carbon black pellet composites, said pellets having a controlled hardness value.

Abstract: A pneumatic tire which makes it possible to effectively prevent puncture during running without involving a large increase in weight or degradation of riding comfortability. This pneumatic tire has a plurality of films disposed in the manner of fish scales in at least a region corresponding to a tread portion of an inner surface of the tire, each of the films being partially fixed on the inner surface of the tire, the fixed portions of the films being covered by the non-fixed portions of the other films.

Abstract: An improved method for the construction of tire liners (19) incorporating a core strip (10) of high temperature and pressure (HPT) molded and vulcanized rubber or another tread supporting material which allows low temperature and pressure (LPT) vulcanizable rubber to flow and to bond the core in place in the liners is described. The tire liner preferably includes LPT vulcanized rubber (16, 17 and 18) surrounding the HPT strip (10) with flexible wings (16) on the side resulting from the flow of vulcanizable LPT rubber during molding of the tire liner. The LPT rubber as vulcanizable sheets 11 and 12 is preferably wrapped around the strip of HPT rubber in such a manner that during molding the rubber flows to the short sides (10b) of the HPT core to form the flexible LPT wings on the tire liner. The tire liner is adapted for mounting inside pneumatic tires adjacent the tread (102) to provide protection against objects penetrating the tread and to stabilize the tread.
