Abstract

"PNEUMáTICO PARA RODAS DE VEìCULOS, E, BANDA DE RODAGEM PRé-MOLDADA PARA REMOLDAR PNEUMáTICOS DESGASTADOS". Um pneumático de alto e médio desempenho para veículos compreende uma banda de rodagem fornecida com uma zona central de largura predeterminada, nas bordas da qual duas zonas intermediárias e duas zonas de ressalto se estendem. Cada zona intermediária compreende duas seq³ências de pares de sulcos transversais, primeira e segunda respectivamente, alternando em sucessão pelo comprimento circunferencial do pneumático; cada par é feito de dois sulcos, pelo menos parcialmente paralelos. Os pares de sulcos da primeira seq³ência começam na zona de ressalto e terminam dentro da zona intermediária e os pares de sulcos da segunda seq³ência começam nas bordas da zona central e terminam dentro da zona intermediária a uma distância predeterminada do sulco mais longo dos pares da primeira seq³ência. A configuração dos pares de sulcos é tal de forma a determinar duas nervuras circunferenciais em zig-zag e uma pluralidade de partes contínuas se estendendo alternativamente a partir de ambos os lados de cada nervura."PNEUMATIC FOR VEHICLE WHEELS, AND, PRE-MOLDED Treadmill to remold worn tires". A high and medium performance tire for vehicles comprises a tread provided with a central zone of predetermined width, at the edges of which two intermediate zones and two shoulder zones extend. Each intermediate zone comprises two sequences of pairs of transverse grooves, first and second respectively, alternating in succession through the circumferential length of the tire; each pair is made up of two grooves, at least partially parallel. The groove pairs of the first sequence begin in the shoulder zone and end within the intermediate zone and the groove pairs of the second sequence begin at the edges of the central zone and end within the intermediate zone at a predetermined distance from the longest groove of the pairs of the first sequence. The configuration of the groove pairs is such as to determine two circumferential ribs in zigzag and a plurality of continuous parts extending alternatively from both sides of each rib.
