摘要： A tire includes at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition including: (a) an amount higher than or equal to 30 phr, preferably 40 phr to 100 phr, of at least one polyisoprene rubber; (b) an amount lower than or equal to 70 phr, preferably 0 phr to 60 phr, of at least one diene elastomeric polymer other than the polyisoprene rubber (a); (c) an amount higher than or equal to 30 phr, preferably 40 phr to 120 phr, of at least one carbon black reinforcing filler; (d) 0.2 phr to 10 phr, preferably 1 phr to 5 phr, of at least one copolymer of at least one ethylenically unsaturated carboxylic acid or a derivative thereof with at least one ethylenically unsaturated monomer containing at least one polyoxyalkylene side chain. Preferably, the structural element is a tire's sidewall.
