Abstract

Un battistrada per pneumatici per autoveicoli presenta una pluralità di tasselli (7) distribuiti secondo file circonferenziali (3, 4, 5, 6) parallelamente affiancate. Il numero di tasselli (7) predisposti in ogni fila aumenta gradualmente passando dal piano equatoriale (X-X) ai bordi laterali (1a) del battistrada (1). Viene così conferito un graduale incremento della rigidità longitudinale dei tasselli (7) passando dai bordi laterali (1a) del battistrada (1) al piano equatoriale (X-X), con una conseguente riduzione della loro mobilità sull'area d'impronta, ed una maggior silenziosità del pneumatico in esercizio.
