A pneumatic tire for ice-bound or snow-covered roads, which has fine grooves formed in a tread surface, thereby improving brake and drive performance on ice-bound roads in early periods of wear. This pneumatic tire for ice-bound or snow-covered roads has its tread partitioned into a plurality of lands, these lands being formed with sipes, wherein the tread surface at the lands is formed with a plurality of fine grooves shallower than the sipes, the edges of these fine grooves being curved. Further, the width of the openings of the fine grooves is larger than the width of the bottoms thereof. Further, the angle of the fine grooves with the circumferential direction of the tire is 42 to 60 degrees.
L'invention concerne un pneumatique pour routes bloquées par les glaces ou pour routes couvertes de neige. Ce pneumatique présente des rainures fines formées sur la surface de la semelle, permettant d'améliorer la performance de freinage sur des routes prises par des glaces, au début de la période d'usure. Ce pneumatique présente une semelle divisée en une pluralité de zones, ces zones étant formées de lamelles, la surface de la semelle au niveau des lamelles étant formée d'une pluralité de rainures fines moins profondes que les lamelles, les bords de ces rainures fines étant incurvés. En outre, la largeur des ouvertures situées dans les rainures fines est plus large que la largeur des fonds. L'angle des rainures fines dans la direction périphérique du pneu est compris entre 42 et 60·.
