AI Technical Summary
Technical Problem
Existing high-contrast textured surface elements on tires suffer from reduced visual contrast due to smooth areas and sensitivity to surface aggressions, leading to degradation and increased manufacturing costs.
Method used
A tire with a high-contrast textured surface element featuring cavities recessed relative to the tire surface, with a specific depth-to-pitch ratio and narrow interface zones, ensuring deep black visual effect and resistance to wear.
Benefits of technology
The solution enhances visual contrast and durability by minimizing light reflection and reducing wear, while maintaining consistent appearance over time.

Abstract
The present invention relates to a tire (1) for a vehicle, the tire comprising, on an outer surface (2), at least one high-contrast textured surface element (3) comprising a texture having cavities (4) recessed relative to the outer surface (2) and adjacent to one another so as to form a network of cavities, each cavity (41) having a depth H and opening onto the outer surface (2) via an opening (41), two openings (41) adjacent to one another being separated by an interface zone (5) and being spaced apart from one another by a pitch P, characterized in that the ratio H / P between the depth H of any cavity (4) and the pitch P between two cavities (4) adjacent to one another is greater than or equal to 1 and in that any interface zone (5) between two openings (41) adjacent to one another has a width Li, measured on the outer surface (2), of less than or equal to 0.050 mm.
