Abstract

Perfeccionamientos en neumáticos para vehículos automóviles, que comprenden una carcasa y una banda de rodaje, caracterizados esencialmente por el hecho de constituir esta banda de rodaje por dos porciones circunferenciales y mutuamente contiguas, de las que una primera porción está formada por una composición elastómera apta para desarrollar adherencia sobre suelo nevado y/o helado, en tanto que la segunda porción está constituida por una composición elastómera apta para desarrollar adherencia sobre suelo seco y/o mojado, estando dotada la primera porción circunferencial , en correspondencia de la superficie exterior, de un dibujo diferente del de la superficie exterior de la segunda porción, estando la temperatura de transición del segundo orden de la composición elastómera de la primera porción comprendida entre -30 y -55ºC, y la temperatura de transición del segundo orden de la composición elastómera de la segunda porción, comprendida entre -10 y -25ºC.
