Abstract: A tire (1) made of rubber material, comprising a tread (2) and a sidewall (3), said tire (1) comprising a marking (4) on the tread (2) and/or said sidewall (3). The marking (4) is divided into a plurality of basic zones (50) of the same size, each basic zone (50) being able to be inscribed in a circle of diameter equal to 8 mm, each basic zone (50) comprising between 0 and N motifs (6), said motifs being formed integrally with the tire so as to define a grey level (Nx) of the basic zone (50) from N+1 grey levels (Nx), the grey level of a basic zone (50) depending on the number of motifs present in this basic zone (50). The marking (4) on the tire comprises at least 5 different grey levels.

Abstract: A tire made of rubber material, comprising a tread (2), said tread (2) having a plurality of grooves (21), each groove (21, 23) having a groove bottom, walls flanking the groove bottom and transition regions between the walls and the groove bottom. The tire is characterized in that all or some of the grooves (21, 23) comprise a texture (3) extending only over the groove bottom and over at least a part of the transition regions associated with this groove bottom, said texture (3) contrasting with the rest of the tire (2).

Abstract: Exterior surface of tire sidewalls have protuberances alternating with voids. The protuberances are arranged between points A, B and C, D. Point A is at the intersection of the radially exterior surface of the tire tread and of the sidewall. Radial axis ZZ? is distant from equatorial plane AA? by length LA of between ½ (L?20 mm) and ½ (L?80 mm), L being the external section width. Point B is at a radius greater than or equal to [R1+0.1 (RA?R1)] and less than RA, R1 being the radius at the external section width and RA being the radius at the point A. Point C is at a radius less than or equal to [R1?0.1(R1?R2)], R2 being the radius of the top of the rim flange. Point D is at a radius in the range R2<D<R2+0.25(R1?R2).

Abstract: The invention relates to a tire tread for a passenger vehicle comprising a tread surface designed to come into contact with a ground when this tire is running. The tread comprises at least one internal cavity of elongate overall shape with a total length LC and width WC and a sipe less than 2 mm wide beginning partly or totally on the cavity. The sipe extends the cavity over the whole of the length LC while extending radially outwards in order to emerge on the tread surface. The cavity comprises a bottom and two lateral walls surrounding this bottom and extending in the length LC of the cavity. The bottom comprises a message intended for an observer of the tire and the message is at a distance from at least one lateral wall of the cavity, the distance between the message and the said lateral wall being at least equal to 5% of the width WC of the cavity.
