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.

Abstract: Polymeric composition comprising a polyolefin and a diacid-diol aliphatic-aromatic copolyester with aromatic part consisting mainly of terephthalic acid or its derivatives, aliphatic part consisting of azelaic acid, sebacic acid and brassylic acid and diol C2-C13. Said copolyesters are particularly compatible with polyolefins, in particular with isotactic polypropylene, in the absence of compatibilising agents.
