Abstract

La présente invention se rapporte aux pneumatiques pour roue de véhicule. Dans ce pneumatique du type dont les flancs travaillent principalement à la compression et sont dépourvus de renforcement, de préférence du type à section trapézoïdale, les flancs sont faits au moins en partie d'une composition élastomère possédant un module d'élasticité dynamique à la compression sous l'effet de sollicitations cycliques dont la valeur absolue est comprise entre 8MPa et 13MPa et dont la tangente de l'angle de perte est comprise entre 0,03 et 0,15. L'invention s'applique notamment aux pneumatiques moulés par injection.
