Tire () comprising a tread (), the tire comprising at least one groove (), at least one wear indicator () disposed in the groove (), the wear indicator comprising a contact face () intended to come into contact with a roadway when the tire reaches a wear limit, the groove () comprising a texture () produced integrally with a bottom () of this groove (), said texture () surrounding the wear indicator () and contrasting with the contact face () of the wear indicator.

Tire comprising a textured tread

A tire made of rubber material includes a sidewall and a marking protruding from this sidewall. The tire has a texture, which has a plurality of strands protruding from the sidewall, these strands being distributed at a density at least equal to five strands per square millimeter (mm), each strand having a mean cross section between 0.0007 mmand 0.06 mmand/or the texture having a plurality of substantially mutually parallel lamellae protruding from the sidewall, the spacing of the lamellae being less than or equal to 0.5 mm, each lamella having a mean width between 0.03 mm and 0.3 mm. The texture protrudes from the sidewall of the tire, and this texture surrounds all or part of the marking.

Tire comprising high-contrast marking

Die () representing a tread pattern model for a tread of a tire to be molded, said die being made up of a die body () and at least one insert () attached to the body of said die, covering at least one of the surfaces of the grooves () in the body (), the insert having at least one substantially flat surface provided with textures.

Die having textured inserts for manufacturing a textured mould for moulding and vulcanizing tires

A tire made of rubber material, comprising a tread (), said tread () having a plurality of grooves (), each groove () 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 () comprise a texture () extending only over the groove bottom and over at least a part of the transition regions associated with this groove bottom, said texture () contrasting with the rest of the tire ().

Tire including a high-contrast texture in a groove

A tire comprising a carcass reinforcement () surmounted radially on the outside by a crown reinforcement (), itself radially on the inside of a tread () having two axially outermost ends. The crown reinforcement () has a layer of reinforcing elements. The tread is connected to two beads () by two sidewalls (), each bead () comprising at least one circumferential reinforcing element. Sidewalls () comprise, on their exterior surface, a series of protuberances () alternating with voids (). The tread () comprises, at least at one axially outermost end (), a circumferential groove (), wherein each protuberance () is positioned at the surface of a sidewall, the different protuberances being arranged regularly or irregularly and continuously between a point A and a point E, and wherein at least one protuberance () partially or completely interrupts or does not interrupt the circumferential groove ().
