Abstract

a presente invenção se refere a um pneumático para veiculo de uso agrícola, e, mais especialmente, a sua banda de rodagem e visa melhorar o compromisso entre a resistência ao desgaste, no centro da banda de rodagem, em uso de estrada, e a resistência às agressões mecânicas, nos ombros da banda de rodagem, em uso no campo; de acordo com a invenção, a banda de rodagem (2) compreende uma primeira porção mediana (21) que tem uma largura axial l1, pelo menos igual a 0.25 vez e no máximo igual a 0.75 vez a largura axial l, e segundas e terceiras porções laterais (22, 23), que se estendem respectivamente axialmente para o exterior, a partir da primeira porção mediana (21) até uma extremidade axial (e, e?), e que têm larguras axiais respectivas (l2, l3); cada porção de pequena barra (311), axialmente compreendida na primeira porção mediana (21) e que se estende radialmente para o interior, a partir da face de contato (6) até uma primeira interface (7), em uma distância radial d1 pelo menos igual a 0.5 vez e no máximo igual a 1 vez a altura radial h de pequena barra, é constituída por uma primeira mistura elastomérica; cada porção de pequena barra (321), axialmente compreendida em uma das segunda ou terceira porções laterais (22, 23) e que se estende radialmente para o interior, a partir da face de contato (6) até uma segunda interface (8), em uma distância radial d2 pelo menos igual a 0.5 vez e no máximo igual a 1 vez a altura radial h de pequena barra, é constituída por uma segunda mistura elastomérica.
