摘要： A tire comprising at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) 100 phr of at least one elastomeric polymer; (b) from about 0.1 phr to about 120 phr, preferably from about 20 phr to about 90 phr of at least one reinforcing filler; (c) from about 1 phr to about 80 phr, preferably from about 2 phr to about 60 phr of glass flakes having an average thickness equal to or lower than 5.0 µm and an average aspect ratio higher than 1. Preferably, said structural element is selected from: bead filler, tread band, tread underlayer, antiabrasive layers, sidewalls, or sidewall inserts.

摘要： The present invention relates to a tyre for vehicle wheels, comprising: - a carcass structure of a substantially toroidal shape, having opposite lateral edges terminating in respective bead structures, said carcass structure comprising at least one carcass ply; - a belt structure applied in a radially external position with respect to said carcass structure, said belt structure comprising at least one belt layer; - a tread band applied in a radially external position with respect to said belt structure; - a pair of sidewalls applied laterally on opposite sides with respect to said carcass structure; - a substantially air-impermeable layer applied in a radially inner position with respect to said at least one carcass ply; - a layer of sealing material applied in a radially inner position with respect to said at least one carcass ply and, preferably, in a radially outer position with respect to said air-impermeable layer; wherein said sealing material comprises: from 55 phr to 95 phr, preferably from 65 phr to 90 phr, of at least one natural or synthetic elastomer; from 5 phr to 45 phr, preferably from 10 phr to 35 phr, of at least one pre-crosslinked elastomer, preferably a styrene-butadiene elastomer; from 5 to 50 phr, preferably from 20 phr to 40 phr, of at least one tackifying agent, and from 1 to 40 phr, preferably from 5 to 30 phr, of at least one reinforcing filler.
