Vehicle pneumatic tire (4) for a wheel system (1) having a rim (2), the vehicle pneumatic tire (4) mounted on the rim (2), and a support device (5) mounted on the rim (2) axially inside the vehicle pneumatic tire (4), which absorbs load during emergency running, wherein the vehicle pneumatic tire…
The insert has annular segment-shaped sub-elements that are either hinged together or clamped together by a clamping system. A T-shaped crossbar (5) is provided as running surface for tire. A concave mold (6) with lateral end points (7) is used for mounting on a rim (8) and resting in assembled…
Support bodies which, in the hollow space within a tire, stably hold for a long period of time a system, etc. for reducing the noise of the tire are configured so that the support bodies can be mass-produced, are simple, and are low cost. A tire (01) is mounted to a wheel (02). The black-filled…
The wheel (1) has an outer envelope (5) with two circular free edges (8) supported on two circular lateral shoulders (4) of a rim (2). A tread (9) is placed between the envelope and the rim. The tread has a contact surface (10) engaged with an inner surface (7) of the envelope, and a bead (11)…
The insert has a radial inner face for surmounting a wheel rim (20) receiving a tire (10). Inflatable circumferential cavity (4) is adapted to be inflated by an inflation valve (26) of an independent wheel of the insert by an inflation gas supply unit (8) emerging on an inner radial face and into…
A tire support ring (5) for pneumatic tires in the event of loss of inflation pressure is disclosed. The support ring (5) comprises an annular main body (7) and a plurality of noise dampers (9). The main body made (7) is made of an elastic material and provided on both sides thereof with a…
A run flat safety support ring (10) intended to be mounted on a wheel rim (12) inside a tire (14) equipping a vehicle for supporting the tire tread in case of loss of inflation pressure has a generally cylindrical crown (18) intended to come in contact with the interior of the tire tread in the…
A runflat tire system (1) comprises:a pneumatic tire (2);a wheel rim (3) on which the pneumatic tire is mounted; anda support ring (5) made of elastic material and disposed in a cavity (4) surrounded by an inner surface of the rim and an inner surface of the tire mounted thereon, whereinthe support…
The present invention provides a shock absorber loaded in the inner cavity of a tire enclosed by a tire for a two-wheeler and a rim, which exhibits suitable hardness when starting running and is excellent in cushioning property, both when starting running and during running, due to decrease in…
A light safety support has an annular body with a continuous support element linking a base to a top. The element has axially extending partitions on either side of its circumferential median plane to improve resistance to buckling under radial loading. The element may be of zig-zag form.
There is provided a tire-rim assembly capable of stably running over a distance required even in the dropping of the tire internal pressure after the injuring of the tire without sacrificing rolling resistance and ride comfort in the usual running before the injuring of the tire, wherein a great…
