Run Flat tyres are specifically designed to remain functional, with a puncture, for a limited period of time. The self-inflating tyres are designed to give you approximately 50 miles after having a puncture allowing you some time to get to a nearby garage or to get home safely.
This can prevent you being stranded at the side of the road with a puncture. Run flat tyres have a reinforced sidewall that will to hold the cars weight when the pressure drops.
Your TPMS (tyre pressure monitoring system) will alert you when the tyre has a puncture or limited air inside. A warning will appear meaning you need to replace the tyre as soon as you can. You should never exceed a speed of 50 mph when this happens.
You would need a TPMS sensor when using run flat technology and you may be modifying your vehicle if you put standard tyres on a car that was intended to have run flats. You will also need to inform your insurance company to make sure your policy is still valid after the modification. All four tyres will need to be replaced when reverting to standard tyres after having run flat technology.
If you unaware if your car has run flat tyres then we can help you.
Run flat tyres are designed to have a similar lifespan to regular tyres. We still recommend you carry out the same monthly checks to make sure you are aware of their condition.
