Abstract

Un pneumatique ne comporte ni bavure ni trace de bavure sur une surface de flanc du pneumatique et réduit la résistance à l'air. Le pneumatique comprend une pluralité d'évidements du type alvéole et une pluralité de parties creux linéaires. Les évidements du type alvéole (16) se situent dans une première région (R1) comprenant une position de largeur maximale de pneumatique de la surface de flanc du pneumatique. Les parties creux linéaires qui sont formées par dentelure de la surface de flanc s'étendent de façon linéaire dans une même direction dans la première région (R1) et sont disposées autour de chaque des évidements (16) de manière à enfermer chacun des évidements. Lorsqu'une taille d'une superficie occupée de chacun des évidements sur la surface de flanc est représentée par un diamètre équivalent d'un cercle, une distance d'intervalle entre les parties creux linéaires est inférieure au diamètre équivalent.
