Definitions

  • a circumferential direction is a direction perpendicular to the meridian plane.
  • the block (6) is provided with forty two incisions (12) at both of the frontal faces (8, 9), that is, twenty one incisions (12) at each of frontal faces (8, 9), the incisions (12) circumferentially extending to be open to one of the sub grooves, that is, the incisions (12) being one side open incisions, wherein the opening width (wl) is 0.4 mm, and wherein a ratio of the sum of the opening widths of the incisions (12) on each of the lateral faces (8, 9) to the block width (BW) is about 35%.

Abstract

La présente invention concerne un pneumatique (1) ayant une adhérence améliorée sur la glace fondante, dans lequel chacun des blocs (6) d'une bande de roulement (2) du pneumatique (1) comprend une pluralité d'incisions (12) s'étendant de façon circonférentielle pour former des ouvertures vers l'une de sous-rainures (5) au niveau des deux faces frontales (8, 9) du pneumatique (1), chacune des ouvertures a une largeur d'ouverture (wl), un rapport de la somme des largeurs d'ouverture (wl) des incisions (12) sur chacune des faces frontales (8, 9) à une largeur de bloc (BW) est compris entre 10 % et 60 %, les incisions (12) ont une profondeur (dl) s'étendant de façon circonférentielle, et une hauteur (hi) s'étendant radialement, un rapport de la profondeur (dl) à une longueur de bloc (BL) est compris entre 0 et 30 %, un rapport de la hauteur (hi) à une hauteur de bloc (BH) est supérieur à 50 %.
