Abstract

a presente invenção refere-se a um pneu para rodas de veículos, em particular veículos motorizados, distinguido por uma banda de rodagem compreendendo, pelo menos, um copolímero elastomérico de iso-estireno/trans-butadieno com um teor de estireno maior do que 30% em peso, com relação ao peso total de copolímero e um peso molecular maior do que 500.000. referida banda de rodagem é distinguida por um comportamento dinâmico-mecânico melhorado em altas temperaturas, com maiores valores de histerese e módulo dinâmico e, ao mesmo tempo, melhores propriedades em ruptura, elasticidade ótima em baixa temperatura e maior resistência à abrasão.
