Puncture repair on a run flat?

[Fordo]

Only just bought me car, and notice yesterday one of the rears looked low - checked, zero psi. The run flat detection system didn't work, so presumably wasn't calibrated.

I have no idea how far I've gone on it - i drove quite gently around yesterday, enjoying the sun. It's kind of impressive what run flats do really, i couldn't tell I had a puncture at all

They can be repaired if the sidewall is sound but if its been driven completely flat I doubt it will be repairable

Had a run flat repaired in the past as long as it's not near the side wall (Mine was a nail in the middle of the tread and cost about £25). Main dealers and major tyre places won't touch them and will try to sell you new ones. Take it to an Indy and hopefully it will save you a lot of money.

It will be goosed if driven on flat for any more than a few miles . once removed there will be a crease where tread meets sidewall along with rubber dust inside , i wouldn't want to risk driving on it at any reasonable speed , bitter pill but time for a replacement

Shame you missed it OP - I had a Pirelli RFT on my 1 Series repaired for £10 a few years ago (which was a big relief)!

But as has been said if an RFT is driven flat it is scrap.

Balls - It's probably beyond repair then. - I'm lucky enough to have a tyre place opposite, so i'll at least get them to have a look.

It was goosed - The inside was full of crumbs of rubber!

Two new non run flat's it'll be.

This. Look out for a running crease along the inside of the tyre.

Just had the same problem on my 330d on a trip to the Lake District. New tyre £225. I was told that although it is possible to repair a runflat, once it is repaired, It is no longer classed as a runflat. In the event of an accident there could be insurance issues. Had a word with my local tyre place and they confirmed they won’t repair them. So even if you find someone to carry out a repair I wouldn’t take the chance.

I’ve got one before, maybe last year or before? I noticed it straight away when I was at work (could hear it). Must have picked it up on the industrial estate road. The guy said it was a pallet nail so makes sense.

Drove it straight over to the tyre place down the road. They repaired it because you could still hear the air escaping but obviously advised I get a new one if possible.

Interesting thread.

When I got my puncture in my 123d it only triggered the light about 2 miles from home, so it still had plenty of pressure in it. I pumped it right up (slightly over pressure) before I drove 5 or so miles to the tyre place that repaired it and they didn't say anything about it not being considered a runflat any more. I was pleased because it was barely half-worn!

Anyway I had it on the car for another 11K miles with no issues, and that included some fairly spirited driving at times!

Mind you it was a Pirelli - they do seem much better than the horrible Bridgestones!

I've had 2 repairs done on my wifes run flats. Both separate tires, both fixes were done with a internal patch. Tires, including RFTs can be plugged to repair a nail hole. But, this method weakens the internal threads in the tire. My wife used tire gunk to repair a nail hole, and ruined the tire monitor in the tire. It had to be replaced or the entire system would not work. The cost was only about $80.00 for the monitor.
