A tire has a rim protector which is formed at a sidewall and which constitutes, an annular protrusion that extends in a tire circumferential direction. The rim protector has not less than two recesses that extend toward the tread region from a location toward the bead region in such fashion as to be directed toward a location in a second direction from a location in a first, direction in the tire circumferential direction, the not less than two recesses being arranged with spaces therebetween in the tire circumferential direction. A mutually adjacent pair of recesses among the not less than two recesses are in a positional relationship such that they partially overlap as seen when projected onto a virtual plane perpendicular to a tire radial direction.

A rim assembly for a bicycle wheel includes a rim and a cover. The rim includes a radially inner portion disposed along an inner circumference of the rim, a first sidewall, and a second sidewall spaced apart from the first sidewall. The first sidewall and the second sidewall extend radially outward form the radially inner portion. The rim also includes a radially outer tire engaging portion disposed along an outer circumference of the rim and. The radially outer tire engaging portion extends from the first sidewall and the second sidewall, respectively. A portion of the radially outer tire engaging portion defines a well disposed between the first sidewall and the second sidewall, opposite the radially inner portion. The rim assembly also includes a cover disposed in the well of the rim. The cover includes one or more openings that extend at least partially through the cover.

A running set comprising: a tire (10) comprising two beads (20); a mounting rim (500) of which the width is greater than or equal to 55% and less than or equal to 80% of the maximum axial width of the tire inflated to its service pressure; and at least one adapter (100) which provides the connection between the mounting rim and a bead of the tire.

An inflation valve for a tubeless tire may include a valve body defining a cavity having a proximal opening and a distal opening. A valve stem extends through the cavity and includes a plug at a proximal end of the valve stem. The proximal opening of the cavity is defined by a beveled surface, and an outer diameter of the beveled surface is larger than an inner diameter of the valve body. The valve is transitionable between: a) a closed position, where a resilient surface of the plug engages the beveled surface to seal the cavity, and b) an open position, where the resilient surface of the plug is spaced from the beveled surface to unseal the cavity.

A rim for a tire for means of displacement preferably for heavy loads at low-speed. The rim may include a main tubular body having a cylindrical surface extending between two lateral edges, a bead-seat having a greater diameter than the cylindrical surface of the tubular body and overlapped to it and at least a side-ring being overlapped to one of the lateral edges for the lateral containment of the tire. The rim may include compensating means interposed between the cylindrical surface of the tubular body and the bead-seat and in contact with them to realise a compensation in thickness.

An adapter for a rolling assembly having an axis of rotation (YY) comprises an axially inner end connected to a rim, an axially outer end comprising an outer reinforcing element and intended to come into contact, via a substantially radial axially inner face, or bearing face, with a bead, a body connecting the axially outer end to the axially inner end so as to form a single piece, comprising at least one main reinforcement providing the connection between the outer reinforcing element and the inner reinforcing element, and comprising a substantially axial adapter seat intended to come into contact with a bead. The outer reinforcing element (15) is completely axially on the outside of the bearing face (21), and the outer reinforcing element (15) is a substantially annular structure, referred to as a bead wire, of substantially polygonal section, comprising at least two first layers of composite and/or metallic material, and at least two second layers of rubber compound, the said first and second layers being arranged mutually parallel and in alternation with each other and parallel to the axis YY.

An inflatable tubeless tire includes a carcass, a bead at the lower edge of both sides of the carcass; a cladding layer, continuously covering the bead from the exterior to the interior of the carcass, and both ends of the cladding layer having an overlapped portion between each carcass and a tread and continuously extending to form an external covered portion for covering an area from the outer surface to the bead, and the portion of both sides of the cladding layer covering the interior of the carcass being an internal covered portion, and the uncovered position in the carcass being an elastic portion, and each inner surface in the carcass and the cladding layer jointly forming a gas chamber; at least a separator, partially disposed on a wall surface of the gas chamber for isolating each elastic portion and the inner surface without sticking to one another of the carcass; an air valve module, passing between each opening and the through hole, and having a film fixed to the elastic portion; and an extending part, passing through each film, the cladding layer and the separator; a screw, with an end screwed into the extending part; and the screw having an air valve part therein.
