Abstract

pneu para veículo agrícola de uso misto. a presente invenção refere-se a um pneu (1) para veículo agrícola compreendendo uma banda de rodagem (2) constituída por blocos (31, 32, 33), separados dois a dois por concavidades (41, 42, 43, 51, 52) e organizados na largura da banda de rodagem (2) ao longo de uma fileira mediana (21), duas fileiras intermediárias (22) e duas fileiras laterais (23). de acordo com a invenção, para obter um balanço ótimo entre a resistência ao rolamento e a vida útil ao desgaste, no uso rodoviário, dois blocos (31) consecutivos da fileira mediana (21) são separados por uma concavidade transversal (41) que tem uma largura (e1) no máximo igual a 2,5 mm, em que o estreitamento circunferencial médio de qualquer bloco (31) da fileira mediana (21) é pelo menos igual a 0,95 e no máximo igual a 1,15, todo bloco (32) de cada fileira intermediária (22) compreende uma face de ataque (321), no sentido circunferencial de rolamento do pneu, formando, com uma direção radial (zz?) do pneu, um ângulo médio (d2) pelo menos igual a 30°, e o estreitamento circunferencial médio de qualquer bloco (33) de cada fileira lateral (23) é no máximo igual a 0,9.
