Wheels with run-flat tyres let you continue driving after a puncture for between 30 and 50 km, depending on the Audi model.
Wheels with run-flat tyres allow you to drive on with a punctured tyre. Instead of changing the wheel or waiting for help in a blind bend or on the motorway, you can continue your journey as far as the next repair workshop.
The run-flat distance is between 30 and 50 kilometres, depending on the Audi model. The tyres are able to run flat due to a reinforced sidewall. The increased sidewall strength prevents the tyres from becoming dislodged and being destroyed in the event of pressure loss. It also improves directional stability when a tyre is running at zero pressure.
Wheels with run-flat tyres replace the spare wheel.
