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.
