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.

In a method for characterizing a surface comprising a localized unevenness, a contour line of the surface is initially created as a function of a location variable (10). Subsequently, the localized unevenness is detected in the contour line (12) and eliminated from the contour line (14), so that an incomplete contour line results as a function of the location variable, which characterizes the surface without the localized unevenness. The incomplete contour line may be used to either be able to evaluate the surface without any localized points of unevenness, for example to determine the side wobble or height wobble of a tire, if the surface is a side flank and / or a running tread of a vehicle tire, or to classify the localized points of unevenness without any influence of the surface.

A system and method for reducing the magnitude of one or more harmonics of one or more uniformity parameters in a cured tire involves selective removal of tire material at one or more track / area locations along first and second bead profiles. Selective removal may occur via ablation at the bead seat, low flange and / or high flange zones to correct for a selected number of harmonics of such parameters as radial, lateral and tangential force variation. Ablation patterns are calculated and implemented on first and second tire beads to achieve desired levels of force reduction at selected angular locations (within the expanse from 0-360 degrees along each tire bead). Ablation patterns may be calculated for implementation at fixed or varied tire rotational speeds and / or fixed or varied levels of laser power.

Provided is a tire pressure sensor (TPS) of a tire pressure monitoring system (TPMS). The TPS includes a detachable and angle-adjustable tire valve coupled to the front side of a tire pressure sensor housing. A holder bracket having a tire valve insertion hole is at the front side, and an insertion head inserted into the valve insertion hole is at an end of the tire valve. Accordingly, the angle of the tire valve is freely controlled, allowing compatible use regardless of the shape or size of wheels of cars and commercial vehicles. Thus, manufacturing costs can be greatly reduced, thereby obtaining superior competitiveness over competitors' products. Furthermore, air leakage through a wheel valve hole can be effectively prevented against high speed rotation and inertia motion caused by the high speed rotation during the driving of a vehicle.

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.

The invention can reduce cost and interference.

An excess tire air pressure relief valve positioned on an automobile tire for relieving the pressure within the tire caused by heat or over inflation. The valve has a main tube that extends through the tire rim, to selectively communicate air from the tire interior to the tire exterior. The tube has a spring that extends between a pair of disks. A seal is positioned below the spring support disk and is pressed against a lower lip by the spring to prevent air leakage through the tube. The spring is selected to exert sufficient force against the seal to prevent air leakage through the main tube. When internal pressure is greater than normal within the tire, the spring is urged outward, allowing air to escape around the edges of the spring support disk until the internal pressure lowers such that the spring can once again hold the seal tightly against the bottom lip.

A tire pressure indicator that is combined with a fill valve. The indicator and the fill valve are coaxial or concentric. The invention may be screwed onto a tire valve stem. The indicator has three bands or sections, each of which is a different color, for indicating whether tire pressure is within a predetermined range, above that range, or below that range. The colors are viewed through a lens, aided by a mirror. A diaphragm pushes the indicator up when pressure rises, while a spring pushes the indicator down when pressure drops. A tire may be inflated or deflated while the invention is mounted on a tire stem. During inflation, the pin in an air chuck at the end of an air hose may depress a valve pin assembly to open the fill valve. A user may deflate the tire by manually depressing the valve pin assembly to release air.

A mud flap lifting system for trucks pushes the mud flaps from their inside surface upward and rearward away from the rear tires. Push bars swing about a pivot from the underside of the truck body directly behind the mud flap. The push bars include C-shaped arms which receive the upper portion of the folded mud flap as it is retracted. Fully retracted, the mud flap is compactly folded so that it is less susceptible to damage. The lift mechanism is pneumatically powered by a single centrally-located cylinder which actuates twin linkages on either side of the truck through a transverse pivoting axle so that both mud flaps may be retracted simultaneously by a single pneumatic actuator.

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.
