Run-flat tires on the BMW X5.

Say goodbye to roadside tire changes. Thanks to special side-wall reinforcement, the BMW X5's standard run-flat tires are capable of being driven a long distance even after a puncture. The benefits make themselves felt far beyond that. The need for a spare tire is eliminated, reducing weight and freeing boot space on every single journey. In addition, the standard Tire Pressure Indicator (TPI) warns the driver whenever there is a drop in tire pressure.
