Abstract

banda de rodagem (1) para pneu destinado ao equipamento de um veículo off-road e que tem uma largura total (w) e uma espessura total de matéria a ser desgastada pelo menos igual a 60 mm, em que essa banda de rodagem é delimitada axialmente por regiões de borda (5) dotadas de ranhuras (7). essa banda de rodagem (1) compreende, em uma região central (6), uma ranhura estreita (61) e, entre cada região de borda (5) e a região central (6), uma região intermediária (4) na qual é formada uma pluralidade de ranhuras estreitas oblíquas ou transversais (411, 412), em que essa banda é tal que: - a ranhura estreita (61) da parte central é constituída por primeiras partes de ranhura estreita (611) que têm uma profundidade (p1) e por segundas partes de ranhura estreita (612) que têm uma profundidade (p2), em que a profundidade (p1) é maior que a profundidade (p2), e em que - as ranhuras estreitas (411, 412) de uma mesma região intermediária compreendem, na direção circunferencial, uma alternância de ranhuras estreitas (411) de uma primeira profundidade (p11) e de ranhuras estreitas (412) de uma segunda profundidade (p22).
