摘要： A method of mounting a tire on a rim includes selecting a tire comprising bead cores, stretching the bead cores, sliding the bead cores over a balcony portion of the rim, allowing the bead cores to elastically return to lengths corresponding to diameters of respective seats of the rim, and inflating the tire. The bead cores include one or more portions of material with characteristics of superelasticity and shape memory. Stretching the bead cores may include applying constant load to the bead cores at ambient temperature and/or causing the bead cores to undergo structural change at ambient temperature. The structural change may include complete or partial change from austenitic structure to martensitic structure. The one or more portions of material are deformable at ambient temperature in response to a constant force and recover to original shape upon removal of the constant force.

摘要： A tire for a vehicle wheel, capable of withstanding the load at low pressure or zero pressure, includes a carcass, a crown, two axially opposed sidewalls, two bead cores, two compression-resistant annular reinforcing elements, and, optionally, a belt structure. The annular reinforcing elements are made of material having high rigidity and very low elastic hysteresis. Each annular reinforcing element is in or adjacent to a zone joining the crown to a sidewall and in a first plane parallel to an equatorial plane of the tire. Each bead core is in a second plane parallel to the equatorial plane. The distance between the first planes is greater than or equal to the distance between the second planes. A camber of an arc between a bead core and an intersection of a carcass ply line with a cylindrical surface passing through the reinforcing elements does not exceed 15% of the arc length.

摘要： In a tire for motor-vehicles, an auxiliary support element (9) is interposed between a carcass ply (3) and a belt structure (6). The support element is employed during the manufacturing step of the belt structure (6) in order to stably retain, on the sectors of a comb drum (10), coils (7a) consecutively formed by winding of an inextensible cord (7) therearound. The auxiliary support element (9) is made in the form of an elastomeric sheet containing short aramid fibers in an amount included between 1 and 10 parts by weight per 100 parts of elastomeric material, to increase the stretchability of said element without impairing its adhesiveness. The introduction of the short aramid fibers in the blend enables the thickness of the auxiliary support element (9) to be reduced to about 0.075 mm.

摘要： A planar sheet comprises a plurality of polyamide yarns having a yarn modulus of from 3.7 to 6.8 N/dtex, an elongation to break of from 2.9 to 4.7% and a denier of from 130 to 15,000 and a plurality of steel wires wherein the steel wire is provided with a first crimp and a second crimp, the first crimp lying in a plane that is substantially different from the plane of the second crimp. The first and second crimp pitches and amplitudes of the steel wire are such that, when the steel wire and polyamide yarns are combined, the elongation to break of the wire is similar to that of the polyamide yarn. The wires and yarns are arranged such that they are oriented parallel to each other within the planar sheet. The sheet has utility in the construction of elastomeric components for tires and belts.

摘要： A method of foreseeing and controlling wearing in the tread of a tire based on the use of cuts of a limited depth (in the order of tenth parts of one millimeter) formed on the external surface of the tread, in the thickness of the elastomeric material. The cut is preferably made by a laser beam. Rotation of the tire on a road or on any other friction surface enables both the uneven wearing of the tread, highlighted by localized spots devoid of cuts, to be quickly verified by inspecting the maintenance state of said cuts, and the wear rate of the tread, which can be drawn from calculation of the time elapsing between the disappearance of two groups of cuts of different depth.

摘要： A tire includes a toroidal carcass and a tread band. The toroidal carcass includes a central crown and two sidewalls terminating in a pair of annular beads. Each annular bead includes a metallic bead core for anchoring to corresponding bead seats of a wheel rim. The metallic bead cores include at least one annular portion made of a material having characteristics of superelasticity and shape memory. The material having characteristics of superelasticity and shape memory is deformable at ambient temperature in response to a constant force and recovers to an original shape upon removal of the constant force to facilitate mounting the tire on the wheel rim. The wheel rim includes a central cylindrical channel from which branches off, axially and outwardly, from opposite sides, diverging surfaces each terminating in a peripheral flange. The diverging surfaces form the bead seats for respective annular beads of the tire.
