Embodiment Construction

[0033] In all illustrations shown in the figures, the curvature of the side walls has been neglected.

[0034] The present invention relates to surface elements formed on the outer surface of pneumatic tires for vehicles and having a specific contrasting structure.

[0035] In this case, the surface element is formed on an area, eg of the outer surface, which does not come into contact with the ground, or does not come into full-surface contact with the ground during use of the pneumatic tire for vehicles. It is particularly preferred that the surface elements are formed on the sidewalls of pneumatic tires for vehicles. Sidewalls of pneumatic tires for vehicles often include characters representing prescribed information, such as dimensional information, speed index, manufacturer, use (summer / winter tyres) or other characters (such as logos or design elements). Surface elements with a contrasting structure can surround the characters mentioned on the side walls, or can form t...

Abstract

The invention relates to a pneumatic tyre for a vehicle, having at least one surface element (2) which is formed on the outer face of the tyre and has a contrast structure (6) which gives the surface element (3) a roughness. In the case of such a tyre, a contrast structure having a much improved contrast effect should be provided. This is achieved in that the contrast structure (6) is an extensive, non-uniform peak-and-trough contrast structure (6) having an areal roughness value Sa according to EN ISO 25178 of 50 mum to 150 mum.

Description

technical field [0001] The present invention relates to a pneumatic tire for vehicles having formed on its outer surface at least one surface element having a contrasting structure imparting roughness to the surface element. Background technique [0002] It is known that surface elements with a contrasting structure can be formed on the outer surface of a pneumatic tire for vehicles, in particular on the sidewall, said surface elements mainly having an The task of contrasting the surface area is optimized so that, for example, it is easier to distinguish symbols on the side walls in this way, such as design elements or logos. Surface elements with a contrasting structure make this possible because they reflect less light than smooth surfaces, that is to say "trap" incident light, and thus appear darker to the observer than smooth surface areas. [0003] A pneumatic tire of the type mentioned at the outset for vehicles is known, for example, from US 2012 / 0227879 A1. At leas...
