Abstract: A rim protector for a wheel of a vehicle, the rim protector (10) being of the form of a generally circular annulus having an axis (1) defining radial and axial directions, the rim protector comprising a tail portion (32), sized to fit in use between the wheel (3) and a tire (2) fitted to the wheel, and a head portion (31), the head portion (31) being wider than the tail portion, the tail portion extending away from the head portion, in which, when the rim protector (10) is fitted to a wheel (3) such that the tail portion is held between the wheel (3) and the tire (2) and the head portion (32) abuts a rim of the wheel (4), the head portion (31) overlaps the rim (4) and extends further radially over the rim (4) than it does over the tire (2).

Abstract: A sealing ring for a vehicle wheel having a tubeless tire with two tire beads that are embodied on the radially inward side thereof. The tubeless tire is mounted on the radially outer side of the multipart rim by the tire beads. The vehicle wheel further comprising a sealing ring which seals the tire radially inward towards the ring, is positioned on the radially outer side of the rim, extends in a peripheral direction along the circumference of the rim and runs between the two tire beads in an axial direction. The sealing ring is configured with a central ring member which is provided with a cylindrical inner surface that is to rest on the outer surface of the rim while being embodied with one respective concentric flexible annular leg which is located on both axial sides of the central ring member and extends diagonally and radially outward in an axial direction from the central ring member.

Abstract: A wheel and tire assembly for recreational vehicles, such as mountainboards, motorized carts and pedaled carts is provided. The tire comprises a tire made of substantially inelastic material that will not stretch under a load. Thus, the tire will flatten under a load to provide a high level of traction on soft and irregular surfaces, as well as on hard and flat surfaces. The tire includes protrusions on its inner diameter surface for securely engaging the wheel. The wheel includes a rim that supports the tire and includes protrusions for engaging the protrusions of the tire in an interdigitating manner. The interdigitating engagement of the protrusions on the tire with the protrusions on the wheel prevents slippage and rotation of the tire relative to the wheel. The wheel also includes support flanges that extend radially inward from the rim in order to protect the tire from damage as the tire deforms under a load.

Abstract: A sealing strip to be used with the rim of a wheel, particularly the rim of a so-called box section bicycle rim, as well as a rim equipped with such a sealing strip, and a wheel having such rim and sealing strip. The sealing strip is formed by a continuous annular strip having, in cross section, a median depression, forming a U-shaped radial groove provided to be positioned within in the central well of the rim, two lateral extensions provided to be supported upon on the interior edges of the rim that border of the well, and two lateral walls provided to extend along the flanges of the rim. The walls of the sealing strip are extended by a pair of lips that project toward the inside relative to the walls of the sealing strip, the lips being adapted to be positioned adjacent the lips of the rim.

Abstract: A rolling assembly includes a rim and a unit that can be slid axially onto and off the rim. The unit includes the tire and a collar on which the tire is mounted. The collar includes opposite collar hooks interconnected by a reinforced central portion of the collar. The hooks receive respective tire beads. When the tire is at reduced pressure, the unit can be inserted onto the rim. Upon inflation of the tire, a blocking portion of the tire enters a groove of the rim to axially lock the tire onto the rim.

Abstract: A rolling assembly formed of a tire P, a narrow rim J, the width of which is at most equal to 50% of the maximum axial width of the tire inflated to its operating pressure, and two connecting elements or adapters A which form the join between the mounting rim J and the beads of the tire P. The adapters A are formed of reinforced rubber mixes which are elastically deformable at least in both the radial and axial directions.

Abstract: A tire apparatus for driving a vehicle is provided. The tire apparatus allows the vehicle to be driven during periods of both low tire pressure and normal tire pressure. The tire apparatus has a tire that has a tread section. The tire has a pair of side walls that are located adjacent to the tread section. A first bead is located at an end of one of the side walls, and a second bead is located at an end of the other side wall. A wheel is also present that has a rim with a first bead seat and a second bead seat. The wheel is configured for attachment to the vehicle. The wheel has a support member for engaging the tire during periods of low tire pressure. At least one of the first and second bead seats has a plurality of friction members to prevent relative rotational movement between the tire and the rim.

Abstract: A rim having a bearing support located between its two rim seats, which bearing support is intended to receive a support ring, is characterized in that this bearing surface comprises at least one surface clamping part, each surface clamping part being regularly distributed in the circumferential direction over the bearing surface and having a maximum external development Ds, measured on an enveloping surface concentric to the bearing surface, which is greater than the development Dp of the bearing surface, in order to create mechanical clamping between a support ring and the surface clamping part which is appropriate to ensure holding of the ring on the bearing surface during travel.

Abstract: The invention relates to a tubeless bicycle tire and rim. The rim is formed with opposing recesses configured to engage corresponding beads formed on the tire. With the beads engaged in the recesses, the tire and rim seal for form an air tight, sealed chamber such that no inner tube is necessary. The rim is formed with a single aperture having a valve installed therein. Preferably, the valve is formed with a ring which extends into the air tight, sealed chamber. In the event of a flat tire, the tire may be removed from the rim. The valve may also be removed by grasping the ring and pulling.

Abstract: A bicycle wheel rim includes a rim body having an annular spoke-mounting wall and spaced left and right annular tire-retaining walls, and a pair of wear-resisting rings. The spoke-mounting wall has two annular lateral peripheral edges. The left and right annular tire-retaining walls extend integrally, radially, outwardly and respectively from the lateral peripheral edges of the spoke-mounting wall. Each of the tire-retaining walls has an inner surface that faces the other one of the tire-retaining walls to confine a tire receiving space therewith, an outer brake pad contacting surface opposite to the inner surface, and an annular end face distal to the spoke-mounting wall. Each of the tire-retaining walls further has a tire retaining projection, formed at a corner of the end face and the inner surface for engaging a bicycle tire so as to retain the bicycle tire between the tire-retaining walls. The wear-resisting rings are made of a resilient material.
