How far can you travel on a run flat tyre?

Distance and speed limits for run flat tyres

Standard limits

Most run flat tyres are designed to allow you to continue driving after a complete loss of pressure for:

• Up to 50 miles (approximately 80 kilometres)
• At a maximum speed of 50 mph (80 km/h)

This is generally enough to get you from most locations to a nearby garage without needing a roadside tyre change.

Important safety notes

• The exact limits vary by manufacturer, so check the tyre documentation or sidewall markings for your specific tyres
• Exceeding the distance or speed limits risks permanent damage to the wheel rim and tyre structure
• The TPMS dashboard light will alert you when pressure has dropped. Reduce your speed immediately when you see this warning.
• Avoid sharp cornering, heavy braking and motorway speeds when driving on a deflated run flat

After driving on a deflated run flat

Once you have driven on a deflated run flat, the tyre will almost certainly need replacing, even if it appears intact externally. Have it inspected at a garage as soon as possible.
