Title (EN) TYRE FOR VEHICLE WHEELS
(FR) PNEU POUR ROUES DE VÉHICULE
Abstract:
(EN) A tyre (100) for vehicle wheels, in particular for sports vehicle wheels for rally races on soft and/or low-grip road surfaces, comprises an equatorial plane (P) and a tread band (101) having a first annular shoulder portion (Al) arranged on one side of the equatorial plane (P) and a second annular shoulder portion (A2) arranged on the axially opposite side to the first annular shoulder portion (Al) with respect to the equatorial plane (P). The first annular shoulder portion (Al) comprises a first block (110) extending mainly along a substantially circumferential direction. The second annular shoulder portion (A2) comprises a pair (140) of block portions (141a, 141b) extending mainly along a substantially axial direction. The second annular shoulder portion (A2) also comprises a transversal groove (160) arranged between the block portions (141a, 141b). The ratio between the circumferential width of the transversal groove (160), measured on any circumferential plane that intersects said pair (140) of second block portions (141a, 141b), and the circumferential width of at least one block (141a, 141b) of said pair (140) of second block portions (141a, 141b), measured on any circumferential plane that intersects said pair (140) of second block portions (141a, 141b), is greater than, or equal to, about 0.5.
(FR) L'invention concerne un pneu (100) pour roues de véhicule, en particulier pour des roues de véhicule de sport utilisé dans des courses de rallye sur des surfaces de route meubles et/ou à faible adhérence, comprenant un plan équatorial (P) et une bande de roulement (101) ayant une première portion d'épaulement annulaire (A1) disposée sur un côté du plan équatorial (P) et une deuxième portion d'épaulement annulaire (A2) disposée sur le côté axialement opposé à la première portion d'épaulement annulaire (A1) par rapport au plan équatorial (P). La première portion d'épaulement annulaire (A1) comprend un premier bloc (110) qui s'étend principalement le long d'une direction sensiblement circonférentielle. La deuxième portion d'épaulement annulaire (A2) comprend une paire (140) de parties de bloc (141a, 141b) qui s'étendent principalement le long d'une direction sensiblement axiale. La deuxième portion d'épaulement annulaire (A2) comprend également une rainure transversale (160) disposée entre les parties de bloc (141a, 141b). Le rapport entre la largeur circonférentielle de la rainure transversale (160), mesuré sur un plan circonférentiel quelconque qui croise ladite paire (140) de deuxièmes portions de bloc (141a, 141b), et la largeur circonférentielle d'au moins un bloc (141a, 141b) de ladite paire (140) de deuxièmes portions de bloc (141a, 141b), mesurée sur un plan circonférentiel quelconque qui croise ladite paire (140) de deuxièmes portions de bloc (141a, 141b), est égal ou supérieur à environ 0,5.
