Abstract

Pneumatico per autoveicoli con un profilo di battistrada, i cui elementi di profilo presentano intagli aventi lunghezza diversa. Questi intagli possono essere combinati con intagli più sottili. Tramite una distribuzione irregolare di questi intagli, le frequenze di vibrazione dell'elemento di profilo sono distribuite in un largo spettro di frequenze, per cui, tramite di essi, il livello di rumore del profilo del pneumatico viene di gran lunga ridotto. (Fig. 1)
