Abstract

''PNEUMáTICO''. A presente invenção apresenta um pneumático (T) que compreende uma parte de banda de rodagem tendo um perfil de banda de rodagem que inclui estrias circunferentemente contínuas; estrias laterais (1) e outras estrias (2). A parte de banda de rodagem é reforçada por uma carcaça tendo pelo menos uma camada (5), e por uma cinta tendo pelo menos duas camadas de trabalho (61, 62). As camadas de trabalho (61, 62) se estendem transversalmente sob todas as estrias, e se estendem além de uma linha limite (7). A espessura (T) da banda de rodagem entre a parte radialmente extrema interna da camada de carcaça (5) e a superfície radialmente externa (10) não se afasta da espessura (T~ c~) no ponto central em mais de 10%. A parte de banda de rodagem do pneumático é moldada de forma que a superfície radialmente externa da estria lateral e das demais estrias define um perfil transversal que é substancialmente plano.''Pneumatic''. The present invention features a tire (T) comprising a tread portion having a tread profile that includes circumferentially continuous grooves; side grooves (1) and other grooves (2). The tread portion is reinforced by a carcass having at least one layer (5), and by a belt having at least two working layers (61, 62). The working layers (61, 62) extend transversely under all the grooves, and extend beyond a boundary line (7). The thickness (T) of the tread between the radially extreme inner part of the carcass layer (5) and the radially outer surface (10) does not deviate from the thickness (T ~ c ~) at the central point by more than 10%. The tread portion of the tire is shaped so that the radially external surface of the side groove and the other grooves define a transversal profile that is substantially flat.
