Abstract

L'invention concerne des pneumatiques pour roues de véhicules. Ces pneumatiques sont du type comportant une bande de roulement divisée en deux parties circonférentielles dont la première est faite d'une composition élastomère conférant une bonne tenue de route sur sol enneigé et/ou verglacé, la seconde étant faite d'une composition élastomère permettant une bonne tenue de route sur sol sec et/ou mouillé. Les deux parties diffèrent également par la forme de leurs surfaces extérieures. Suivant l'invention, les températures de transition du deuxième ordre des compositions élastomères sont de - 30 à - 55 degrés C pour la premiere partie destinée à la stabilité sur sol enneigé et/ou verglacé et de -10 à - 25 degrés C pour l'autre partie. L'invention s'applique notamment aux pneumatiques pour véhicules automobiles.The invention relates to tires for vehicle wheels. These tires are of the type comprising a tread divided into two circumferential parts, the first of which is made of an elastomeric composition giving good road holding on snowy and/or icy ground, the second being made of an elastomeric composition allowing good road holding on dry and/or wet ground. The two parts also differ in the shape of their outer surfaces. According to the invention, the second order transition temperatures of the elastomeric compositions are -30 to -55 degrees C for the first part intended for stability on snowy and/or icy ground and -10 to -25 degrees C for the first part. other part. The invention applies in particular to tires for motor vehicles.
