Abstract

"PNEUMáTICO PARA VEìCULOS" A invenção se refere a uma banda de rodagem para pneumáticos, compreendendo em cada lado do plano equatorial uma fileira de blocos centrais e uma fileira de blocos intermediários entre uma fenda longitudinal central e um par de fendas laterais longitudinais. Os blocos das fileiras centrais são separados dos blocos das fileiras intermediárias por meio de um par de sulcos circunferenciais e os blocos das fileiras centrais e intermediárias são circunferencialmente espaçados por meio de uma pluralidade de fendas transversais muito profundas. O padrão da banda de rodagem compreende blocos das fileiras intermediárias que são circunferencialmente escalonados em relação aos blocos das fileiras centrais e blocos das fileiras centrais que são circunferencialmente escalonados com relação um ao outro. As fendas transversais têm linhas de centro que são inclinadas em um ângulo (<244>) em direções opostas uma à outra com relação a um plano perpendicular ao plano equatorial."VEHICLE PNEUMATICS" The invention relates to a tread for tires, comprising on each side of the equatorial plane a row of central blocks and a row of intermediate blocks between a central longitudinal slot and a pair of longitudinal side slits. The blocks of the central rows are separated from the blocks of the intermediate rows by means of a pair of circumferential grooves and the blocks of the central and intermediate rows are circumferentially spaced by means of a plurality of very deep transverse slits. The tread pattern comprises blocks of the intermediate rows that are circumferentially staggered with respect to the blocks of the central rows and blocks of the central rows that are circumferentially staggered with respect to each other. The transverse slits have center lines that are inclined at an angle (<244>) in opposite directions from each other with respect to a plane perpendicular to the equatorial plane.
