The present invention relates to an airless tire which supports load by an internal structure of the tire, comprising: an outboard tire; a plurality of spokes connected to the inside surface of the outboard tire; and a column foot for increasing the contact area of the spokes and the outboard tire. Therefore, localized bending deformation caused by the stress formed by the spokes can be prevented, uniformity of the airless tire can be improved, and the radial run-out performance is improved.

A tire includes a foam portion made of rubber or plastic material and foamed integrally to be a ring-shaped foam portion, and a resilient portion received in the foam portion and having a hollow space defined therein. The hollow resilient portion reduces the foam material required and provides proper resilient feature to keep shape of the tire.

The present turbine fan rim, turbine fan airless tire and turbine fan hubcap designs are configured to remove air from under the underside of a moving vehicle when rotated in a particular direction, typically in a forward direction. This air movement can create a vacuum below the vehicle, which can create a down force on the vehicle increasing traction between the vehicle's tires and the road surface and lowering the vehicle's center of gravity. This downward force and partial vacuum can thus increase as the rotational velocity of the tires increases, providing greater traction at higher speeds. An additional benefit to these wheel, airless tire, and hubcap designs is the cooling effect that would be created by the flowing air on brake parts that are located near wheels of nearly all vehicles.

A tire pressure monitoring system comprising a sensor located inside a tire of a vehicle may be operable to measure one or both of a temperature inside the tire, and flexion of the tire. The tire pressure monitoring system may be operable to calculate an air pressure inside the tire based on one or both of the measured temperature and the measured flexion. Communications between the sensor and other components of the tire pressure monitoring system may be wireless, such as, for example, via an ISO 18000-7 link. The sensor may be embedded in the tire (e.g., in the sidewall, in the tread, or in the liner). The sensor may measures flexion of the tire at a point (e.g., the point where the tire meets the ground) where the tire is being compressed and at a point (e.g., the point opposite where the tire meets the ground) where the tire is not being compressed.

In a rear vehicle body structure for a vehicle using a torsion beam suspension system, a laterally extending slot is defined between a vertical front wall of a spare tire pan defined in a rear floor panel and a raised rear end of a front floor panel, and a torsion beam of the torsion beam suspension system is received in this slot. The spare tire is received in the spare tire pan in a rear end up slanted orientation. A rear end cross member extends across the vehicle in a rear end of the spare tire pan. In a rear end collision, the spare tire pan is pushed forward by the rear end cross member. The rear end cross member enables the impact load to be evenly distributed to the spare tire pan or the rear floor panel.

The invention relates to an automobile tire pressure monitoring system which adopts the Bluetooth technology, in particular to a low-power consumption tire pressure monitoring system of a large vehicle with the number of tires more than eight, comprising a sensor module and a Bluetooth transmitter module which are arranged in each automobile tire and a Bluetooth receiving module which is arranged on an automobile bridge. The pressure monitoring system has the advantages that as frequency domain extension of the Bluetooth is operated, the sensor in each tire can accurately communicate with a receiver on the automobile bridge, thus avoiding the mutual interference of the sensors of all the tires and the interference of the tire pressure sensors of the adjacent automobiles; and a master micro-network and a slave micro-network of small range of the Bluetooth also can carry out topological extension, thus being easy to establish a plurality of tire pressure monitoring systems.

A method is provided for generating a ground compaction image. A pressure sensing panel is placed on a relatively rigid planar supporting surface. The pressure sensing panel is covered with a depth of particulate material. A loaded tire is placed on the particulate material, and a ground compaction image is generated with the pressure sensing panel. A ground compaction display may be created by superimposing the ground compaction image on a physical three-dimensional model of an interface between the particulate material and the loaded tire.

A pneumatic tire (100) has a tread, a carcass (200) with belt plies (230) disposed below the tread (500), and a cap ply layer (300) between the tread and the belt plies of the carcass. The cap ply (300) is a weft inserted warp knit fabric tape (310) comprising an in-lay warp yarn set (312), a weft inserted yarn set (313), and a stitching yarn set (311), wherein the stitching yarn set forms a repeating stitch pattern on each warp yarn comprising a sequence of at least 2 stitches around the warp yarn from one stitching yarn and at least 2 stitches around the warp yarn from the adjacent stitching yarn. The tape (310) is wound in a flat helically wound around the belt plies (230) and covered with a tread (500) of the tire.

An insert specifically adapted for use with an off-road tire, such as an off-road tire of a motocross motorcycle, or an off-road bicycle. The insert includes an inflatable tube and a foam element which generally conforms to the contours of the off-road tire to provide support to the tire when the tube is inflated. The ability to deflate the insert facilitates installation of the insert between the wheel rim and off-road tire. When inflated, the insert occupies the space between the wheel rim and tire to support a load during use of the wheel.
