A run-flat tyre is a pneumatic vehicle tire that is designed to resist the effects of deflation when punctured, and to enable the vehicle to continue to be driven at reduced speeds - under 56 mph (90 km/h) - and for limited distances - generally between 10 mi (16 km) to 50 mi (80 km), depending on the type of tyre.
Do I need run flat Tyres?
Fitting 'Conventional' Tyres to a Run Flat Equipped Vehicle
If your car was originally supplied with Run Flat tyres, then it is possible to change to 'conventional' tyres. However, if the vehicle was designed with Run Flat tyres in mind, bear in mind you could be left stranded without a spare!
Can I put run flat tyres on my car?
No - run flat tyres should only be fitted for cars specifically equipped for them. This is because the car will not have TPMS installed and consequently the driver will have no idea if a puncture occurs.
