Disclosed is an anti-puncture shield insert for a wheel. The wheel includes a rim and an inflated tire connected to the edges of the rim. The shield insert is made of a shock-absorbing material. The shield insert is placed at the widest point between the inner sidewalls of the tire. As a hit causes the tire to collapse, the shield insert absorbs the shock taken by the tire and the rim, by staying between inner parts of the tire. The shield insert is floating relative to the tire.

Filling element (“mousse”) for tires of off-road motor vehicles. The filling element is provided with circular grooves. It is made of expanded polymeric material for longlife even under extreme conditions of external temperature, speed of the vehicle and hardness of the ground. It provides improved driving performances in terms of stability and adherence of the tire to the ground even on rough grounds of great hardness.

A system and method for a tubeless tire insert. The present invention includes an annular body having shock absorbing characteristics. A positioning system configured to vary a mean inner diameter of the insert is also included. The insert has a mean inner diameter X when the tire is being installed on the rim, and the insert has a mean inner diameter Y when the tire is installed on the rim, where X is greater than Y.

A vehicle includes: a sensor for measuring a relative position and a relative speed between an obstacle and the vehicle; an injector for injecting a deforming material which is solidified during injection to absorb an impact and enhance coupling strength at a portion to which the deforming material is attached; and a controller configured to determine a collision probability with the obstacle based on the measured relative position and the measured relative speed, to determine a predicted collision position when the collision probability reaches a reference collision probability, to determine an injection direction of the injector based on the predicted collision position, and to control the injector to inject the deforming material in the determined injection direction.

A tire-wheel assembly includes a run-flat support member that is provided with a support surface formed on an outer circumferential side, and that is disposed on a rim in a cavity portion of a pneumatic tire, the run-flat support member being formed by connecting a plurality of foamed bodies in a tire circumferential direction with a band-like member, and being disposed in an annular shape on an outer circumference of the rim.

A tire includes a carcass, side-reinforcing rubber, a belt layer, and a tread. The belt layer includes at least two layers and is provided at a tire radial direction outer side of the carcass, each layer including a cord inclined with respect to a tire circumferential direction such that the cords of the belt layers intersect each other. The tread is provided at the tire radial direction outer side of the belt layer. A tire cross-section height SH satisfies SH≥145 mm, and a ground contact width TW of the tread and a maximum tire width direction width of the belt layer satisfies TW<B. Moreover, an angle θ formed between a tire outer face and the tire width direction at a position at 0.8SH toward the tire radial direction outer side of a bead base portion of either of the bead portions is no less than 60°.

The present invention relates to a hybrid run-flat having a buffering structure for a military vehicle, and more particularly, to a hybrid run-flat having a buffering structure for a military vehicle wherein a buffer member famed of a material different from the run-flat is provided on an outer circumferential surface of the run-flat of the military vehicle to enable a driving due to the buffer member even when a tire punctures, in which a groove for a lubricant is formed on an outer circumferential surface of the buffer member, and a buffer space as an empty space is famed therein, so that the impact relief effect is increased.

An air deflector that is at least partially disposable within a tubeless tire of a bicycle wheel includes a body. The body includes at least one wall defining an air input end and an air output end of the body. The body is attachable to a valve of the tubeless tire at the air input end, such that when air is introduced into the body via the valve, at least some of the air is deflectable by one or more walls of the at least one wall out of the body at the air output end.

A run-flat tire includes a tire casing and a steel rim connected to an opening side of the tire casing to form a cavity, wherein a shock absorbing elastic component is provided along a radial direction in the cavity, one end of the shock absorbing elastic component is connected to the tire casing, and a gap is provided between another end of the shock absorbing elastic component and an outer wall of the steel rim. Specifically, a first annular shock absorbing cushion is provided along a circumferential direction inside the cavity, one end of the shock absorbing elastic component is fixed on the tire casing, and another end of the shock absorbing elastic component is fixed on the first annular shock absorbing cushion; a second annular shock absorbing cushion is provided along the circumferential direction on the outer wall of the steel rim.
