Abstract: Abstract: A label (1; 50) for a tyre (100) of vehicle wheels comprises: at least a first layer (4) which is made of an elastomer material which is compatible with the elastomer material of a sidewall (102) of the tyre, an external surface (2) which is intended to remain visible when the label is coupled to the sidewall, a plurality of recesses (10) which are formed at the external surface (2) and which are capable of generally defining at least one portion of information which is set out on the label (1; 50). The elastomer material of which the first layer (4) is made comprises a quantity of a halogenated isobutylene polymer greater than 5 phr.

Abstract: A label (1; 50) for a tyre (100) of vehicle wheels comprises: an external surface (2) which is intended to remain visible when said label (1; 50) is coupled to a sidewall (102) of the tyre, an internal surface (3) which is opposite the external surface (2), a plurality of recesses (10) which are formed at the external surface (2) and which are not open at said internal surface (3) and which are capable of generally defining at least one portion of information which is set out on the label. The plurality of recesses (10) are formed on a first layer (4) of the label (1; 50) which is made of an elastomer material which is compatible with the elastomer material of the sidewall (102). The first layer (4) is partially vulcanized and has a degree of vulcanization corresponding to a value between T30 and T60.

Abstract: 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 ?m 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.

Abstract: 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.

Abstract: 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°, substantially over the entire length thereof.
