VEHICLE PNEUMATIC TYRE

摘要

The invention relates to a vehicle pneumatic tyre of a radial design having an at least two-layer belt and having a tread (1), wherein the tread (1) has profile grooves (1a) within the axial width of TW 45 for forming profile positives, the maximum depth (12, 13) of said profile grooves varying within the axial width of TW 45, and wherein the tread (1) has an outer contour which is defined on the fitted and inflated tyre by reference to rolling radius differences. The invention is distinguished by the fact that the maximum depth (12) of the profile grooves (1a) within a centre region (9) of TW 45 is the same, that the maximum depth (13) of the grooves (1a) in the shoulder region (10) is a maximum of 2 mm smaller than in the centre region (9), and that the outer contour of the tread in the centre region (9) is made flat such that the outer contour radius difference ArdM between the zenith (S) and the axial end of the centre region (91, 92) is less than 1 mm, and that the outer contour of the tread in the region of the junction with the shoulder region (11) is configured in such a way that the outer contour radius difference (Ards) between the zenith (S) and this junction with the shoulder region is 3 mm to 5 mm.
