The external cavities () have a mean longitudinal length Lm, a depth at least equal to 0.9 Hm, and are separated by internal cavities having a mean longitudinal length Li, Li being at least equal to 0.5*Lm and at most equal to 2*Lm. At least one rib () in the longitudinal direction and delimited by a complex groove with transverse sipes () made at a mean spacing Pm. The spacing Pm of the transverse sipes is at most equal to the mean longitudinal length Lm of the external cavities ().
