pneu a presente invenção refere-se a um pneu que compreende pelo menos um elemento estrutural que inclui um material elastomérico reticulado obtido pela reticulação de uma composição elastomérica reticulável que compreende: (a) 100 ppc de pelo menos um polímero elastomérico; (b) de cerca de 0,1 ppc a cerca de 120 ppc de pelo menos um enchedor de reforço; (c) de cerca de 0,01 ppc a cerca de 20 ppc de pelo menos um derivado de oxetano e (d) de cerca de 0,01 ppc a cerca de 10 ppc de pelo menos um ácido carboxílico. preferivelmente, o dito elemento estrutural é selecionado de: banda de rodagem, sub-camada de banda de rodagem, enchedor de talão, costados e insertos de costado. The present invention relates to a tyre 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 0.01 phr to about 20 phr of at least one oxetane derivative; and (d) from about 0.01 phr to about 10 phr of at least one carboxylic acid. Preferably, said structural element is selected from: tread band, tread underlayer, bead filler, sidewalls, and sidewall inserts.
