A tire having a decreased percentage of void and superior wear abilities, yet still having improved wet traction ability is disclosed. The improved wet traction ability is enhanced by the flow isolating characteristic of the minor grooves of the tire. By reducing the amount of water flow between the major and minor grooves for a prescribed period during which the major grooves evacuate water away from the tire, there is a reduction in the volume and nature of turbulence due to the intersecting water flows exiting the minor grooves into the major grooves. This reduction of turbulence allows for fluid to be properly channeled away from the contact patch area by their major grooves.
Pneu ayant un pourcentage de vide réduit et une résistance supérieure à l'usure, tout en ayant une traction améliorée sur surface humide. La traction améliorée sur surface humide est favorisée par l'aptitude des petites rainures du pneu à isoler les filets d'écoulement de l'eau. Par suite d'une réduction de la quantité d'eau qui s'écoule entre les petites et les grosses rainures pour une période donnée durant laquelle les grosses rainures évacuent l'eau à l'écart du pneu, il y a réduction et modification de la turbulence due aux filets d'eau qui se croisent en s'écoulant des petites rainures dans les grosses. Cette réduction de turbulence permet au liquide d'être bien canalisé à l'écart de la surface de contact avec la chaussée par les grossses rainures.
