摘要:
A tire including at least one structural element includes a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition including: (a) 100 phr of at least one elastomeric polymer; (b) 0.1 phr to 15 phr, preferably 0.3 phr to 10 phr, of at least one methylene donor compound: c) 0.4 phr to 20 phr, preferably 0.8 phr to 15 phr of at least one methylene acceptor compound; (d) 1 phr to 50 phr, preferably 2 phr to 40 phr, more preferably 4 phr to 30 phr, of at least one layered material, the at least one layered material having an individual layer thickness of 0.2 nm to 30 nm, preferably 0.3 nm to 15 nm, more preferably 0.5 nm to 2 nm; wherein the at least one layered material shows, in an X-ray powder diffraction pattern, an X-ray intensity ratio (R) defined according to the following formula: (R)=[A(001)/A(hk0)max]×100 wherein: A(001) is the area of the peak (001); A(hk0)max is the area of the most intense peak (hk0), at least one of h or k being different from 0; lower than or equal to 20, preferably lower than or equal to 15, more preferably lower than or equal to 10, still more preferably lower than or equal to 5. Preferably, the at least one structural element is selected from bead filler, sidewall insert, tread underlayer and tread base.
