Abstract

PNEUMáTICO. Um pneumático tendo (i) um perfil de rodagem assimétrico com uma diferença de queda de ombro de 0,3 a 0,9; e (ii) um padrão de rodagem assimétrico de modo a ter uma relação entre a relação entre espaço vazio/sólido interna e a relação entre espaço vazio/sólido externa de 1,1 a 1,50, por meio da combinação acima de características, desempenho de manuseio e aquaplanagem são extraordinariamente melhorados até mesmo em altas velocidades de operação sem negativamente afetar a resistência ao desgaste da banda de rodagem.
