In a vulcanization mold for vulcanized vehicle pneumatic radial tires having a tread, sidewalls (1), bead regions (2), and at least one fabric layer, in particular with two fabric layers, in the radial carcass, which has an overlapping region in each sidewall region. On each sidewall (1), near the bead region (2) and at the overlapping region, at least one hatching field (4c, 10) is formed with elevations (3) running at least substantially parallel to one another, which have a height (h1) of 0.2 mm to 0.6 mm compared to the smooth areas of the sidewall (1), whereby the hatching field (4c, 10) is bounded at least in part by a raised frame (5, 11) which is at least in regions at least 4 mm wide, which has a smooth surface and over its width and longitudinal extension a constant height (h2), which corresponds at least to the height (h1) of the elevations (3), and which is formed by a recess (8) in the vulcanization mold, in which venting bores (9) with venting inserts (9a) are positioned.
