    摘要： Tire (100) comprising at least one structural element including at least one reinforcing element (106c) comprising at least one hybrid yarn, said at least one hybrid yarn (206) comprising a plurality of filaments obtained from at least one first multifilament yarn (201) having a first initial tangent modulus and at least one second multifilament yarn (202) having a second initial tangent modulus, said first and said second initial tangent modulus being different from each other, each one of said first and said second multifilament yarn (201,202) comprising a plurality of individual filaments, the individual filaments of each one of said first and said second multifilament yarn (201,202) being at least partially intermixed with each other. Preferably, said tire (100) is a high performance (HP) or ultra high performance (UHP) tire, or a tire (100) suitable for being employed in sporting contests such as track motor races, or a tire suitable for Sports Utility Vehicles (SUV).

    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.
