The present invention relates to a tire comprising at least one structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising: (a)100 phr of at least one elastomeric polymer, (b)from about 0.1 phr to about 120 phr of at least one reinforcing filler; (c) from about 0.05 phr to about 10 phr of at least one crosslinking agent selected from the group comprising diazides having the following general formula (I): N3-A -R -B -N3 (I) wherein -A and B, which may be equal or different from each other, are selected from the group comprising: a substituted or unsubstituted methylene group, a substituted or unsubstituted benzyl group, or a substituted or unsubstituted benzylidene group; -R may be alinear, branched, or cyclic alkylene group comprising from 1 to 20 carbon atoms, said alkylene group optionally comprising one or more heteroatoms selected from S, N, or O. Preferably, said structural element is selected from: bead filler, tread 20 underlayer, antiabrasive layers, or sidewall inserts.
