Run-flat tyres on the BMW 1 Series Coupé.

Even after a complete loss of tyre pressure, run-flat tyres retain their shape and remain firmly attached to the rim. Even at higher speeds, the BMW 1 Series Coupé (except model 120d) remains stable and precisely controllable. The car can be driven for up to 150 km at 80 km/h following loss of tyre pressure - or even longer in the case of a slow puncture. The need for a spare tyre is eliminated.
