The present disclosure relates to a tyre comprising a carcass structure, a tread band, a pair of sidewalls and at least one colored decorative element having a thickness equal to or greater than 200 μm applied by co-vulcanization on at least one side of the pair of sidewalls, wherein the pair of sidewalls comprises an elastomeric composition comprising (i) at least one diene elastomeric polymer, and (ii) an ozone protection system, and the at least one colored decorative element is made with a cross-linkable elastomeric composition comprising (i) 100 phr of elastomeric polymer comprising 30 phr to 70 phr of natural and/or synthetic isoprene rubber, and 30 phr to 70 phr of a rubber chosen from butyl rubber, halobutyl rubber, butadiene rubber, styrene-butadiene rubber, and mixtures thereof, and (ii) 5 phr to 120 phr of at least one reinforcement filler.

Tyre for vehicle wheels

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.

A tyre for wheels of vehicles, in particular motor vehicles, is described. The tyre has a tread with at least one iso-styrene/trans-butadiene elastomeric copolymer with a styrene content higher than 30% by weight with respect to the total weight of copolymer and a molecular weight higher than 500,000. The tread has improved dynamic-mechanical behaviour at high temperatures, with higher dynamic modulus and hysteresis values, and at the same time better properties at break, optimum elasticity at low temperature and higher abrasion resistance.

High performance tyre

A tire for motorcycles includes a tread band in which a tread pattern is formed which includes a series of transverse grooves disposed at least laterally of the equatorial plane. The tread pattern on the whole defines a low sea/land ratio on the tread band. The series of transverse grooves includes a plurality of main recesses having an overall length at least equal to one fourth of a lateral extension of the tread band. The main recesses define with the equatorial plane, an angle less than or equal to 65&#xb0;, substantially over the entire length thereof.
