Abstract

A tire comprises at least one structural element made of a crosslinked elastomer material obtained by crosslinking a crosslinkable elastomer compn. comprising (a) 100 phr of at least one elastomer, (b) from 0.1 to 15 phr, preferably from 0.3 to 10 phr, of at least one methylene donor compd., (c) from 0.4 to 20 phr, preferably from 0.8 to 15 phr, of at least one methylene acceptor compd., (d) from 1 to 50 phr, preferably from 2 to 40 phr, more preferably from 4 to 30 phr, of at least one layered material having an individual layer thickness from 0.2 to 30 nm, preferably from 0.3 to 15 nm, more preferably from 0.5 to 2 nm. The layered material shows, in an X-ray powder diffraction pattern, an X-ray intensity ratio R 20, preferably 10, as defined according to the formula R = [A(001)/A(hk0)max] x 100, where A(001) is the area of the peak (001); A(hko)max is the area of the most intense peak (hk0), at least one of h or k being different from 0. Preferably, the structural element is selected from bead filler, sidewall insert, tread underlayer, and tread base.
