ABSTRACT:
A tire which emits reduced travel noise, when moving on a surface, having a tread formed of load-bearing elements distributed over the circumference of the tire in accordance with a plurality of repetitive design cycles of variable pitch is characterized by the fact that the number of each of the principal design cycles of different pitch satisfies all of the n-1 general relationships (B): ##EQU1## and by the fact that the number of each of the design cycles present on the tread satisfies the relationship (C): ##EQU2## it being understood that ##EQU3## and/or .epsilon. may each be equal to zero.
