Abstract
A tire for vehicle wheel includes at least one elastomeric component including a crosslinked elastomeric material obtained by crosslinking an elastomeric composition including at least one diene elastomeric polymer; at least one sulfur-based vulcanizing agent, and at least one adhesion promoting agent having formula HOOC—R—S—R′—COOH wherein each of R and R′, equal or different from each other, is a divalent organic group. In a preferred embodiment of the first aspect of the present invention, the elastomeric component includes a metal reinforcing agent embedded therein.
