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 disclosure relates to a tyre () for vehicle wheels comprising at least one carcass structure (), a tread band () applied in a position radially external to said carcass structure, and a pair of sidewalls () applied laterally on the opposite sides with respect to said carcass structure, where on at least one sidewall of said pair of sidewalls (), a label () is applied comprising a protective layer (), an adhesive layer (), and possibly one or more ink layers () interposed between said protective layer () and said adhesive layer (), where said adhesive layer () adheres the label () to the surface of said sidewall, where said protective layer () comprises polyester-based and/or polyether-based cross-linked aliphatic polyurethanes exhibiting dynamic elastic modulus values E', measured at 25° C., static tensile deformation 1%, dynamic deformation ±0.1%, and frequency 1 Hz, equal to or higher than about 5 MPa, and a residual deformation measured at 25° C. after 4 cycles of deformation from 0% to 12%, equal to or lower than about 1%.
