I think I have a slow puncher on one of my run-flats and looking around on the net there are conflicting opinions and stories of how some repairs have messed with tyre pressure monitors. I don't expect it should mess the monitors because as far as I'm aware the system monitors the tyre circumference.

If they can be repaired where which tyre centres do this? I asked my dealership service people and they are clueless as to the whether you can repair or not.
 
Yeah it'll suck the tyre is pretty new got another 40K+ to go on it. And I hate replacing one at a time.
 
Check with your insurance company of its allowed... Don't risk your insurance over it...

What size tyre btw?
 
You can never repair any tyre with a damaged sidewall.
There's no reason not to repair a run flat if the damage is in the tread provided the sidewalls are good.

With normal tyres you can generally patch it if the damage is on the sidewall. Runflats specifically depend on the sidewall being sound though so patching is a bad idea.

I'm sure you'll find places willing to patch it anyway regardless of safety.

Personally I'd rather not...

What?!?!
You can never patch a sidewall, never.
You can only patch or more accurately plug if it falls within the treated area.
 
And no it's not side wall, it's probably along the tread area somewhere. My insurance will not pay because it will be classified as wear and tear and not accident even though it's the ****ty work road that caused the puncture.
 
Repairing a puncture should cost no more than 50 bucks.
 
Think I've had 6 punctures in my time driving, 4 have been in or close enough to the sidewall to make repair impossible. 3 of those have been runflats, 2 were R5k uninsured Pirellis, the 3rd was 'just' a Conti, only 2.5k. :(

Frigging hate punctures.
 
I had one of my run-flats repaired a couple months ago. The tyre had picked up a loose nail on the road. I was also unsure whether it could be repaired. So I took it to a repair centre and they said yes it is fine to repair a run-flat, and plugged it for R50.

The embarrassing thing is that I'd been driving with those tyres for 4 years and didn't know they were run-flats until the puncture happened. The car drove ok even with the puncture because I hardly go onto the freeway. So I might have driven with the "flat" tyre for a few weeks. Only noticed it one day when I walked past the tyre and noticed that the air pressure looked slightly low. So I went to a garage to top up the air, but the tyre was taking no air. 0 BAR.
 
Run flats with no tyre pressure monitoring should not be allowed

Just shows that the tech is solid...a week of regular driving and maybe a bit of freeway without the user even noticing something is wrong. Much better than a tire blowing out at 120kmh...

Ye, I'm going to swap all 4 run-flats out for normal tyres soon. Normal tyres should reduce the road noise I experience as well.

I try to discourage this among family members. Sure its more comfortable & quieter but I'd prefer loved ones rolling with run flats.

On a side note...recently saw an oke on the side of the road changing a tire in a high visibility jacket...nice demonstration of foresight & safety awareness.:cool:
 
I had a slow puncture repaired in my run-flats on my BMW a few months back. As long as there is no side-wall damage, it's fine.

What car do you drive? Your car should tell you if it looses pressure in one of it's tyres. That's how I knew I had a puncture.

It's a 9 year old 2005 350z which I bought about 4 years ago. The only electronics in the car is the outside temperature reading. :D Oh and the traction control plus cruise control.

So the 350Z has run flats but no pressure monitoring?
