Punctured Run flat repaired

[Srishail Kumar]

I had my minor service today at Lexus Edinburgh and the NSF run flat (a bridgestone) was punctured. Lexus repaired it for but I read later that punctured run flats should be replaced. Should I get a new one ?

Hi Srishail

Run flat tyres can be successfully repaired just like normal tyres. If Lexus has repaired the tyre and told you all is now good then I would trust their advice.

Ive recently had 2 run flats repaired successfully.

I guess provided you haven't driven far on it whilst flat there would be no reason to have it replaced, after all its the sidewalls that are designed to take the weight of the car the tread is like normal tyres.

Thank you for the suggestions. I also was hoping for recommendations on having run flats in front but non run flats in the rear. Is that okay ?

I’ve come away from run flats but I wouldn’t partially do it.   They are very heavy and might alter the dynamics of the vehicle by having a mix.

Ah okay. Guess I’ll move to normal tyres soon as my NSF run flat is a repaired puncture. Will get tyreweld and Lexus RSA for some peace of mind.

My repaired run flat is still going strong 18 months later so I wouldn't be concerned, and it definitely shouldn't be the reason for you to change them soon.

I carry a small electric tire inflator, so if I get a warning of low tyre pressure I can hopefully reinflate it.  This should increase the chances of being able to get the run flat tyre repaired rather than having to replace it.

This is exactly what i did with my slow punctures re-inflate with the tire inflator until i got repaired.

Just come across this topic, but I think this is an important point that Don makes!  As a basic rule, it’s never a good idea to mix different types of tyres.

As to whether RFs are repairable, it seems that the answer is….it all depends on the tyre, why it’s losing pressure and how it’s been driven on!  This explanation by Goodyear might be helpful.
