Zusammenfassung:The present invention relates to a tyre for vehicle wheels comprising at least one external structural element comprising at least one external structural element comprising a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising (i) at least one diene elastomeric polymer, and (ii) a system for protection against ozone substantially free of polymeric static protective agents which essentially consists of at least one phenolic antioxidant in an amount substantially equal to or higher than 3 phr. La presente invención se refiere a un neumático para ruedas de vehículos que comprende al menos un elemento estructural externo que comprende un material elastomérico reticulado que se obtiene por la reticulación de una composición elastomérica reticulable que comprende (i) al menos un polímero elastomérico de dieno, y (ii) un sistema de protección contra el ozono sustancialmente libre de agentes protectores estáticos poliméricos que consiste esencialmente en al menos un antioxidante fenólico en una cantidad sustancialmente igual o mayor que 3 phr.
