Abstract
The invention relates to pneumatic tires for a motor vehicle comprising a multi-layer carcass. Said multi-layer carcass extends between two bead rings, a set of bracing plies provided between the layers of the carcass and a tire tread, and rubber reinforcement layers arranged in the side wall areas which support the tire when it is deflated. The invention is characterized in that a first rubber reinforcement layer is arranged radially within a first carcass layer and a second rubber reinforcement layer is arranged between the first carcass layer and a second carcass layer. The two rubber reinforcement layers extend from the bead filler area to a position under the edge area of the bracing plies. The two rubber layers vary in thickness across the height of the side walls.
