Abstract: A vehicle pneumatic tire includes a tread, ply structure, and radial carcass extending around a bead core in each bead region and extending back under the ply structure. Side wall regions are formed by a wing rubber extending from the side of the tread toward the bead region and a rim protection rubber extending from the bead region toward the wing rubber. The wing rubber is the only rubber component extending to the tread and runs in the radially outer portion of the side wall region in contact with the carcass and covers the adjacent rubber component toward the bead region by the radially inner end section of the wing rubber. The adjacent rubber component includes an end section in the covered region narrowing toward the tread, the end of which is located a distance from a base line between 45% and 70% of the height determined therefrom.
