Abstract

PNEU PARA MINIARO. Trata-se do pneu (11) para um veículo de passageiro que compreende uma camada de trabalho axialmente mais estreita (26), sendo que a camada de trabalho axialmente mais estreita (26) tem uma largura axial T2 expressa em mm. O pneu é adaptado para ser montado (10) em um suporte de montagem (100) que compreende um aro (200) que tem uma largura de aro A expressa em mm e um código de largura de aro de acordo com o Manual de Padrões ETRTO 2019. O pneu (11) tem um índice de carga Ll de modo que LI = LI'+1, LI' que é o índice de carga de um pneu de CARGA EXTRA do mesmo tamanho de acordo com o manual de padrões ETRTO 2019. A razão T2/A se dá de modo que T2/A = 1,00. O código de largura de aro é igual ao código de largura de aro de medição para o tamanho de pneu menos 0,5.
