Abstract
A tyre includes at least one structural element obtained by crosslinking a crosslinkable elastomeric composition including: (a) a crosslinkable elastomeric base comprising at least 10 phr, preferably from 30 phr to 100 phr, of (a.sub.1) at least one epoxidized elastomeric polymer including less than 10 mol %, preferably from 0.1 mol % to 5 mol %, of epoxy groups relative to the total number of moles of monomers present in the elastomeric polymer; and (b) from 2 phr to 50 phr, preferably from 5 phr to 30 phr, of at least one layered material. Preferably, the at least one structural element is selected from bead filler, sidewall insert, tread underlayer, and tread base.
