What are Run Flat Tyres?

by chris sanders on 13th June 2013

It’s hard enough to find the correct tyres for your car but when you get the chance to have Run Flat tyres, that just makes the decision even harder. But what is Run Flat I hear you ask?

Run Flat tyres are made so when they are punctured they still remain with the structure in the tyre. This is only for a small amount of time. This gives you time to get straight to your garage. The best thing about a Run Flat is even if you get a flat tyre it doesn’t disrupt your whole day. It gives you chance to drive to where you need to be.

How do they work?

The modern Run Flats are usable with no air pressure in them thanks to their special reinforced sidewall. In normal tyres, the air is key. Once the tyre loses air the pressure will drop and the structure will fail. This is the difference with Run Flats. The hardened wall is strong enough to keep the whole structure of the tyre. The range on Run Flats obviously varies depending on the tyres. Usually about 50 miles.

Don’t Go Back!

I’d recommend that if your car was originally fitted with Run Flat tyres then you shouldn’t change them. The reason for this is that there’s a possibility that changing the tyres could affect the vehicle’s handling. If you do decide that you don’t want Run Flats then I would consult your manufacturer before you go ahead with the changes.

Can I put them on my old car?

If you are considering the best thing for your old car is to put Run Flats on it then there are a couple of things you need to know first.

As you already know your Run Flat tyres have no air pressure. So when there is a puncture the driver won’t be aware. So to solve this problem there is such a thing called Tyre Pressure Monitoring System (TPMS) and as you only have a limited time to drive the TPMS sensor makes you aware of the problem. But older cars are less likely to have the TPMS sensor. It’s not essential that you have the sensors but it is definitely recommended.

Final Thoughts

If you are looking into getting Run Flat Tyres it is recommended by all garages that you buy one for each tyre. Normal Tyres and Run Flat Tyres have different structural characteristics and will no doubt affect your suspension and handling.

The life span of your Run Flat tyres are very similar to your normal tyres. They’re made from the similar or identical material. So you don’t have to worry about them being worse than the normal tyres.
