Abstract: 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.

Abstract: 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.

Abstract: 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.
