The present invention relates to a tire () for vehicle wheels comprising a tire component comprising a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition, wherein said elastomeric composition comprises a polymer blend comprising (a) 50 to 95 percent by weight of a first elastomeric polymer and (b) 5 to 50 percent by weight of a second elastomeric polymer based on the total weight of the polymer blend. The second elastomeric polymer (b) is obtainable by (i) anionic polymerization of at least one conjugated diene monomer and one or more a-olefin monomer(s) in the presence of a polymerization initiator in an organic solvent, and (ii) coupling the polymer chains obtained in (i) by a coupling agent. The second elastomeric polymer (b) has a weight-average molecular weight (Mw) in the range of 5,000-40,000 g/mol and a coupling rate of at least 50 percent by weight.

Tire for vehicle wheels

Tires for vehicle wheels having reduced environmental impact and the components thereof, in particular reinforcing structural elements such as carcass structures, belt structures, flippers and chafers, include elongated reinforcing elements treated with resorcinol and formaldehyde-free cross-linkable adhesive compositions. The adhesive compositions include at least a) a rubber latex, at least b) an epoxide and at least c) a polyamine with molecular weight higher than 190 Daltons, including at least two amino groups selected from primary &#x2014;NH2 and secondary &#x2014;NH&#x2014; amino groups. In the structural element, these compositions confer an adhesion between cords and compounds that is comparable to, if not better than, the traditional RFL system in use in this sector. Furthermore, by suitably modifying the compound compositions in the reinforced structural elements and, possibly, also in the other elastomeric components of the tire, it is possible to manufacture tires while avoiding the use of toxic chemicals, such, as resorcinol and formaldehyde.
