A carcass layer (4) of the tire starts on the inside of a bead core (5) and runs around the latter to form a turned up end (4a) on the axially outer side of the tire which can be mounted on a standard rim. One or more reinforcing strips (9) with cords are arranged in each bead core area (3) close to and connected to the turned up carcass end. The reinforcing strips surround an annular profile on the axially inner side of the bead core. At least one end (9a,9c) of the reinforcing strip (9) ends radially inside the upturned end of the carcass layer (4). The axially outer end section (9c) of the reinforcing strip ends radially inside or radially outside the other end section (9a). The longer end section (9a) extends not >50% of the height of the tire cross-section. Each annular profile has a drop or triangular shaped cross-section with a center of gravity inside the bead core. A pointed section of the annular profile extends into an area radially inside the bead core (5). Annular profile cross-section is 20-30% of the bead core cross-section. Carcass layers run from the inside to the outside of a single or multi-part core profile(8) situated radially outside the core. A carcass layer may pass between two core profile parts lying radially outside the core.
