Disclosed are an explosion-proof tire hub, including a hub body and an explosion-proof convex retainer. The hub body includes bent portions configured to mount a vacuum tire, the hub body is provided with a central axis, the explosion-proof convex retainer is fixed on the hub body, the distance between an upper end of the explosion-proof convex retainer and the central axis is L1, the distance between an upper end of the bent portion and the central axis is L2, and L1 is greater than L2. In case of burst or instantaneous pressure loss, because the distance L1 between the upper end of the explosion-proof convex retainer and the central axis is greater than the distance L2 between the upper end of the bent portion and the central axis, the explosion-proof convex retainer reduces the distance between the whole hub and the ground during tire burst and improves safety performance.

A braceable run-flat insert for a vehicle wheel has subelements forming a circular ring. The subelements are connected in an articulated manner or braced by a clamping system.

To prevent the ingress of dirt, the cross section of the subelements forms a T shape on the tire side. The crossbar of the T is a running surface for the tire when there is a tire defect. The cross section of the subelements form an approximate T shape on the rim side. Two lateral end points fit on the rim base and rest on the latter in the fitted state. The tire-side T and the rim-side T are connected by a radially running web. The lateral end points of the crossbar of the rim-side T-shaped configuration can be displaced toward one another against a restoring force by an elastic subregion between the two end points of the crossbar.

A tubeless tire on a rim having a hollow core foam insert in the cavity of the tire and a loop of elastic material holding the foam insert in a relatively closed loop against the rim. The foam insert has a length that equals or almost equals the circumference of the rim. The loop of elastic material passes through the hollow core of the foam insert and also has a length that equals the circumference of the rim.

A module, usable with a plurality of other modules, to obtain an annular modular assembly adapted to fill a tire of a cycle or motorcycle. The module can be removably inserted into the tire and includes a body made of foamed elastomeric material defining a portion of the annular modular assembly. The body has a shape of circular or ellipsoidal section with tapered end areas designed, in use, to remain facing or in contact with one of the tapered end areas of the adjacent modules. The tapered end areas define respective planes converging toward the center of the tire and angularly spaced by an angle between 8? and 30?.
