Abstract
The surface state of the treads of tires cured in a vulcanization mold manufactured by 3D printing represents an optimal compromise between cost, appearance, and grip performance of the tire. The texture is formed by an arrangement of contiguous elements of pyramidal shape, each element of pyramidal shape having a base of parallelogram type positioned on the tread surface, and an apex situated at a normal distance H from the base in the range 0.15 mm to 0.5 mm.
