Tyre for vehicle wheels

A tyre for vehicle wheels comprising:

• at least one external structural element comprising a crosslinked elastomeric material, wherein the crosslinked elastomeric material comprises, before vulcanization, a crosslinkable elastomeric composition and the crosslinkable elastomeric composition comprises:
• at least one diene elastomeric polymer, and
• a system for protection against ozone substantially free of polymeric static protective agents, wherein the system consists of only at least one phenolic antioxidant, and the at least one phenolic antioxidant is present in an amount higher than 6 phr and lower than 15 phr,
• wherein the at least one phenolic antioxidant is chosen from:
