Pneumatic tyre for a vehicle

The tire has a protection element (8) in a region of a line (10) to protect a side wall (3) from abrasion contacts over the side wall. An outer contour of a collar region and upper and lower side wall portions (4, 5) of the side wall are designed in a convex-shape with a constant curvature. The protection element is integrated into a contour of the upper side wall portion. The lower side wall portion is arranged in an axially inwardly movable manner opposite to the contour of the upper side wall portion through an axially inwardly stepped stage (9).
