Abstract

trata-se de pneus pneumáticos tendo uma banda de rodagem contendo uma pluralidade de sulcos que se estendem radialmente para dentro de uma ou mais camadas da porção de banda de rodagem que são descritos como tendo melhor resistência ao rasgamento do sulco. a resistência aumentada ao rasgamento de sulcos em ou próximo à extremidade fechada dos sulcos em uma banda de rodagem de pneu pode melhorar o desempenho do pneu durante o funcionamento e por toda sua vida útil. as composições de borracha da uma ou mais camadas da porção de banda de rodagem em contato com um sulco ou sua porção de extremidade terminal contêm talco para aumentar a resistência ao rasgamento em ou próximo à porção de extremidade de um sulco durante o funcionamento.
