Abstract: The tire includes a summit surrounded by side portions terminating in beads provided to cooperate with a mounting rim. A carcass reinforcement is surmounted by a summit reinforcement composed of reinforcing plies. When the tire is mounted onto its standard mounting rim and inflated with its nominal pressure, each side portion has an upper side point, a bottom side point, an intermediate side point, an upper side portion, and a bottom side portion. A weight of the bottom side portion on one side portion is at least 15% lighter than a weight of the bottom side portion on another side portion.

Abstract: A dual, internal, pneumatic, boltless beadlock assembly for effectively securing a tire to a rim is disclosed. A pneumatic beadlock assembly is disposed inside a tire and mounted on a rim. A pneumatic beadlock assembly exerts a force on the two circumferential inner beads of a tire such that the tire stays in secure contact with the rim, even when the inflation pressure of the tire is not sufficient to lock the tire to the rim.

Abstract: An adapter for a rolling assembly having an axis of rotation (YY′), the rolling assembly comprising a tyre having two beads, and a rim having two rim bead seats, for each bead, provides the connection between the bead and the rim, the said adapter comprising an axially inner end connected to the 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 is completely axially on the outside of the bearing face, and the outer reinforcing element is a substantially annular structure, referred to as a bead wire, of polygonal section, comprising an individual metal wire of diameter D1, the said wire being coated in an elastomer composition and wound contiguously around a support at least three times in an axial direction and at least twice in a radial direction.

Abstract: A tire includes a tire frame member that has bead portions in which bead cores are embedded in a resin material and side portions that comprise the resin material and are continuous with tire radial direction outer sides of the bead portions, wherein assuming that T1 is a thickness of thick-walled portions of the tire frame member that are adjacent to the tire radial direction outer sides of the bead cores and that T2 is a thickness of the side portions, T1>T2, a thickness of the tire frame member decreases from T1 to T2 between the thick-walled portions and the side portions, and a position at which the thickness of the tire frame member starts to decrease from T1 to T2 is on a tire radial direction outer side of tire radial direction outer ends of rim flanges of a rim on which the bead portions are mounted.

Abstract: A bicycle tubeless tire includes a tread and two sidewalls are formed on two sides of the tread. Each sidewall has a lip formed on the distal edge thereof. An installation unit is integrally formed with each lip. Each lip includes an inside, an underside and an outside. The underside and the outside of each lip are engaged with an engaging portion at the inner bottom of the rim when the tire is installed to the rim. The lips do not shift by the engaging portions of the rim. Each of the underside and the outside is a flat side such that the contact area between the lips and the rim is increased to have better air-tight features. The outer face of each lip is a flat face to be installed to the rim without flanges. The deformation of the sidewalls of the tire, and the wind resistance are reduced.
