Title (EN) HIGH PERFORMANCE TYRE WITH TREAD BAND HAVING AN ANISOTROPIC UNDERLAYER STABLE UPON TEMPERATURE VARIATION
(FR) PNEU A HAUTE PERFORMANCE A BANDE DE ROULEMENT DOTEE D'UNE SOUS-COUCHE ANISOTROPE STABLE AUX VARIATIONS DE TEMPERATURE
Abstract: front page image
(EN)The invention relates to a high performance tyre which has a structure consisting of the radial carcass (3) with, mounted on it, in a position increasingly towards the outside, one or more belt layers (7) and a reinforcing layer with a nylon cord (8) spirally wound around the belt. Advantageously, the tread band of the tyre is formed by an underlayer (11) and an external layer (12) arranged one upon the other, the former having elasticity and/or hardness characteristics which remain substantially unvaried between 20 °C and 110 °C: in this way the tyre is able to ensure an excellent performance even at the high speeds for which it is designed and that may cause a substantial increase in the temperature of the rubber compound.
(FR)L'invention concerne un pneu à haute performance dont la structure se compose d'une carcasse radiale (3) sur laquelle est montée, dans une position allant croissante vers l'extérieur, une ou plusieurs nappes de ceinture (7) ainsi qu'une nappe de renforcement dotée d'un câblé (8) en nylon enroulé en spirale autour de la ceinture. De façon avantageuse, la bande de roulement du pneu est constituée d'une sous-nappe (11) et d'une nappe extérieure (12) agencées l'une sur l'autre, la première ayant des caractéristiques d'élasticité et/ou de dureté demeurant sensiblement inchangées entre 20 °C et 110 °C. Ainsi le pneu est capable d'assurer une excellente performance même aux vitesses élevées pour lesquelles il est conçu et pouvant provoquer une augmentation sensible de la température du composé de caoutchouc.
