Abstract
PNEU DE MOTOCICLETA. Um pneu de motocicleta (1) é descrito compreendendo um plano equatorial (X-X) e uma banda de rodagem (8) compreendendo uma porção radialmente interna (13) e uma porção radialmente externa (11) compreendendo respectivamente um primeiro e um segundo material elastomérico vulcanizado obtido por vulcanização dos respectivos materiais elastoméricos compreendendo 100 phr de pelo menos um polímero de dieno elastomérico, de 30 a 130 phr de pelo menos uma carga de reforço compreendendo uma quantidade superior a 75% ou, respectivamente, igual ou superior a 80% de uma carga banca. No pneu (1), a razão R1 entre o módulo de elasticidade dinâmico (E) e o tandelta medido a uma frequência de 10 Hz e a 70°C do primeiro material elastomérico vulcanizado está compreendida entre 27 e 35, enquanto a razão R2 entre o módulo de elasticidade dinâmico (E) e o tandelta medido a uma frequência de 10 Hz e a 70°C do segundo material elastomérico vulcanizado está compreendida entre 15 e 30, sendo a razão R1/R2 superior ou igual a 1,1.
