Tire and crosslinkable elastomeric composition comprising diazide crosslinking agents

The tire comprises >=1 structural element including a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric compn. comprising (a) 100 phr >=1 elastomeric polymer, (b) .apprx.0.1-120 phr >=1 reinforcing filler, and (c) .apprx.0.05-10 phr >=1 crosslinking agent selected from diazides N3ARBN3, where A and B, which may be equal or different from each other, are selected from substituted or unsubstituted methylene group, a substituted or unsubstituted benzyl group, or a substituted or unsubstituted benzylidene group; R may be a linear, branched, or cyclic alkylene group comprising 1-20 C atoms, the alkylene group optionally comprising >=1 heteroatoms selected from S, N, or O. Preferably, the structural element is selected from bead filler, tread 20 underlayer, antiabrasive layers, or sidewall inserts.
