Title (EN) TYRE FOR VEHICLE WHEELS
(FR) PNEUMATIQUE POUR ROUES DE VÉHICULE
Abstract:
(EN) Tyre for vehicle wheels, comprising a tread band comprising circumferential grooves, circumferential ribs defined by said circumferential grooves and a plurality of sipes (10) that extend, on said circumferential ribs, from a radially outer surface of the tread band towards a radially inner portion of the tread band. Said sipes (10) extend along a predetermined trajectory and comprise, in any cross section perpendicular to said predetermined trajectory, a main portion (100) having a first radial dimension (H') and a first transversal dimension (T, T') substantially constant along a radial direction and, in a radially outer position with respect to said main portion (100), a top portion (110) extending up to said radially outer surface of the tread band and having, at said radially outer surface of the tread band, a second transversal dimension (W) greater than said first transversal dimension (T, T').
(FR) Pneumatique pour roues de véhicule, comprenant une bande de roulement comprenant des rainures circonférentielles, des nervures circonférentielles délimitées par lesdites rainures circonférentielles et une pluralité de lamelles (10) qui s'étendent, sur lesdites nervures circonférentielles, d'une surface radialement extérieure de la bande de roulement vers une partie radialement intérieure de la bande de roulement. Lesdites lamelles (10) s'étendent le long d'une trajectoire prédéfinie et comprennent, dans toute section transversale perpendiculaire à ladite trajectoire prédéfinie, une partie principale (100) ayant une première dimension radiale (H') et une première dimension transversale (T, T') sensiblement constante le long d'une direction radiale et, dans une position radialement extérieure par rapport à ladite partie principale (100), une partie supérieure (110) s'étendant jusqu'à ladite surface radialement extérieure de la bande de roulement et ayant, au niveau de ladite surface radialement extérieure de la bande de roulement, une seconde dimension transversale (W) supérieure à ladite première dimension transversale (T, T').
