Keep performing even when the pressure drops: run-flat tyres keep you mobile even if all tyre pressure is lost. Instead of an unpleasant and unsafe roadside tyre change, you can reach home safely or drive to the next workshop for assistance.
Run-flat tyres are their own spares: thanks to specially reinforced side walls and additional lateral strengthening, they continue to perform their function even if all air pressure is lost. The heat-resistant rubber compound is able to withstand additional heat build-up.
With run-flat tyres fitted, you can continue driving for up to 150 km at a speed of up to 80 km/h without any significant loss in vehicle stability. You not only save time and stress, you are also free of the need to carry a spare tyre, saving stowage space.
All driver assistants remain fully functional when driving with a loss of tyre pressure. The optional Adaptive Drive system redistributes the load to the other tyres, reducing the burden on the low-pressure tyre as much as possible. The wheel rims of run-flat tyres have special design that ensures the tyre will not detach from the rim, even on tight bends.
Run-flat tyres provide greater safety, more peace of mind and additional cabin space. It's not surprising that Germany's ADAC, the largest automobile club in the world, has described run-flat tyres as the "first important revolution in tyre design since the invention of the pneumatic tyre."
