Title (EN) PNEUMATIC TIRE
(FR) BANDAGE PNEUMATIQUE
Abstract: front page image
(EN)A pneumatic tire has a ground surface formed with at least three zigzag grooves. The ratio (Hs/W) of the height (Hs) of that one (Ms) of the three zigzag grooves which is formed on the side of the tire closest to the shoulder region with respect to the tread width W is specified to be within 2 % to 4 %. Moreover, the ratio (Hc/W) of the height (Hc) of that one (Mc) of the three zigzag grooves which is formed in the tread center with respect to the tread width W is specified to be within 6 % and 10 %. This configuration improves the wet braking characteristics without shortening the working life of the pneumatic tire.
(FR)Un bandage pneumatique possède une bande de roulement comprenant au moins trois rainures en zigzag. Le rapport (Hs/W) entre la hauteur (Hs) de la rainure en zigzag (Ms) qui est formée sur le côté du pneu le plus proche de la région d'épaulement et la largeur (W) de la bande de roulement est compris entre 2 et 4 %. En outre, le rapport (Hc/W) entre la hauteur (Hc) de la rainure en zigzag qui est formée au centre de la bande de roulement et la largeur (W) de la bande de roulement est compris entre 6 % et 10 %. Cette configuration permet d'améliorer les caractéristiques de freinage sur sol mouillé sans écourter la durée de vie du bandage pneumatique.
