An automobile pneumatic tire comprises a multiple-ply carcass extending in-between two bead rings having allocated bead fillers, a belt arrangement between the plies of the carcass and a tread strip, and rubber reinforcement plies in the sidewall sections assuming a supporting function where the tire is deflated. A first rubber reinforcement ply is inside a first ply of the carcass, a second rubber reinforcement ply is between the first ply of the carcass and the second ply of the carcass, and a third rubber reinforcement ply is between the second ply of the carcass and a third ply of the carcass. The three rubber reinforcement plies extend down with their ends staggered in relation to each other from the bead core area to the edge area of the belt ply. The three rubber plies have different heights in radial direction and different thickness over the height of the sidewall.
