Tire made of crosslinkable elastomeric compositions comprising elastomers, silica filler and coupling agents

Tire comprising at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) about 100 phr of at least one elastomeric polymer; (b) from about 5 phr to about 120 phr, preferably from about 20 phr to about 100 phr, more preferably from about 30 phr to about 90 phr, of at least one silica reinforcing filler; (c) from about 0.1 phr to about 10 phr, preferably from about 0.2 phr to about 8 phr, more preferably from about 0.3 phr to about 6 phr, of at least one coupling agent containing at least one mercapto group; said crosslinkable elastomeric composition being substantially free of heavy metals or derivatives thereof, in particular of zinc or derivatives thereof. Preferably, said at least one structural element is a tire tread band.
