Title
(EN) METHOD AND CONSTRUCTION FOR IMPROVED SNOW TRACTION, HIGHWAY WEAR, AND OFF-ROAD PERFORMANCE
(FR) PROCÉDÉ ET CONSTRUCTION PERMETTANT D'AMÉLIORER LES PERFORMANCES EN MATIÈRE DE TRACTION SUR NEIGE, D'USURE SUR AUTOROUTE ET DE DÉPLACEMENT TOUT TERRAIN
Abstract
(EN)
A method of improving the snow traction performance of a tire and tire constructed according to such method are provided. More specifically, a method is provided for constructing the tread of a tire into inner and outer portions that experience different radial deformations under operating conditions so as to improve snow traction and other performance features and also provided is a tire having such tread constructions.
(FR)
La présente invention se rapporte à un procédé consistant à améliorer les performances de traction sur neige d'un pneumatique et à un pneumatique construit selon un tel procédé. L'invention se rapporte plus spécifiquement à un procédé de construction de la bande de roulement d'un pneumatique en parties intérieures et extérieures qui subissent des déformations radiales différentes dans des conditions de fonctionnement de manière à améliorer la traction sur neige et autres performances. L'invention concerne également un pneumatique présentant de telles constructions de bande de roulement.
