Abstract

L'invention concerne une technologie pour améliorer la stabilité de direction, dans laquelle à la fois la réponse du pneu au début du virage et la contrôlabilité du pneu au voisinage du point limite de virage requises pour un pneu à carcasse radiale à performance élevée destiné à une application sur des voitures de performance élevée sont satisfaites. Dans un pneu à carcasse radiale dans lequel au moins deux couches de ceinture de mélange utilisant des câbles d'acier comme matériau de renforcement sont disposées, la rigidité du câble d'acier dans la couche de ceinture par unité de largeur satisfait l'expression suivante : (A-800)/B≥20, dans laquelle, A : rigidité en traction du câble (kg) définie par la contrainte à une traction de 1% x nombre de câbles (par 50 mm), B : rigidité en flexion de câble (g/mm) définie par l'inclinaison de la courbe de déplacement en contrainte-flexion obtenue par un test de flexion à trois points du câble lorsqu'il est poussé de 2-6 mm et déformé x nombre de câbles (par 50 mm).
