<p>A tire for vehicle wheels comprising at least one element made of a cross-linked elastomeric material including a hydrophilic polymer, and an elastomeric composition comprising a hydrophilic polymer employed therein. Preferably, said element is a tread belt. The composition comprises: at least one elastomeric diene polymer; at least one thermoplastic polymer having a main hydrocarbon chain to which hydrophilic groups are linked; at least one polymer containing functional groups reactive with said hydrophilic groups. The hydrophilic polymer is capable of absorbing significant amounts of water, without however dissolving and thus being easily removed from the elastomeric matrix. Besides, the hydrophilic polymer may carry out a reinforcing action of the elastomeric material and may therefore at least partly replace the conventional reinforcing fillers.</p> |
