The present invention provides a simulated inflatable wheel including a rim, a filler tire mounted on the rim, and a tire casing covering the filler tire and having a rolling portion in rolling contact with the external environment and an abutting portion extending from two sides of the rolling portion. The abutting portion is located between the rim and the filler tire. The abutting portion abuts against the rim and the filler tire respectively. A recessed portion is formed on at least one position of an outer surface of the filler tire. The present invention utilizes the recessed portion of the filler tire to generate space between the filler tire and the rim (or the tire casing), for providing a buffer when the filler tire is deformed and improving elasticity of the filler tire. The present invention further provides a stroller including the simulated inflatable wheel.

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.

A motor vehicle tire is disclosed with a pair of post-cure run-flat inserts, each of the pair of post-cure run-flat inserts is disposed within a tire cavity between a shoulder region and a respective upper sidewall region of the tire. The tire further includes a cylindrical sidewall defining an interior cylindrical cavity, each of the cylindrical sidewall and the interior cylindrical cavity extending 360 degrees about a rotational axis of the tire, the cylindrical sidewall having an exterior surface contacting a radially inner surface of an inner liner between the shoulder region and the respective upper sidewall region during a normal inflation condition of the tire.

The invention relates to a run-flat device for a mounted assembly of a motor vehicle and such a mounted assembly incorporating it.

This device comprises a wheel rim having a rim base of diameter D and a tire mounted on the rim, the device being suitable for supporting the tire in a run-flat situation and comprising: a ring comprising a multitude of axial portions juxtaposed over a circumference of the ring and defining an inner mounting face on the rim base and an outer support face of the tire in a run-flat situation, each portion having at least one support situated radially between the mounting and support faces, and at least one belt which surrounds the ring over the circumference thereof so as to support it substantially in contact with the rim base and which passes through the portions by being applied on the supports thereof.

According to the invention, the portions are not hinged to one another and are tight or spaced apart from one another over the circumference by a total sum of consecutive spaces, measured between the portions at the mounting face thereof, which is less than .Math.D/2.

A balanced non-deflatable vehicle tire providing balanced operation even after partial puncture, adjustment of overall air pressure, use of standard rimmed wheels, and the option of being retrofit into existing tires, by providing alternating layers of puncture-resistant sheet material and pressurized-cell sheets, and an inner-tube to fill the remaining internal space and to adjust and apply balanced pressure internally.

A run flat device configured to be fitted to a tubeless mounted assembly for a motor vehicle, which includes a wheel rim and a tire cover including beads mounted against edges of the rim, the run flat device including: an annular supporting structure which is configured to be mounted around the rim so as to support the cover following a drop in inflating pressure inside the mounted assembly, including: three composite spring segments forming sectors in an arc of a circle assembled circumferentially around the rim forming the annular supporting structure by means of transverse pins whose shape geometry is asymmetrical; and an arrangement for locking the beads against the edges which are configured to connect the annular supporting structure to these beads.
