Repair a run flat?

Hello folks. I was rather annoyed to find my tyre pressure light come on the other night, then check my tyres to find one of the run flats with Zero pressure. Worse still, it was one of the rears and the car has only covered 13,000 miles, so really annoyed now. The tyre worked brilliantly though.

I was wondering if anyone has ever had a run flat repaired by a specialist? I went to a garage (kwik fit) who wouldn't touch it, but they suggested that my local BMW garage are able to repair, but i'd have to sign a waiver incase the tyre fails again.

What are people views on having this done?

Also, does anyone know a good supplier for Bridgestone tyres at cheap prices????
 
I've had a runflat repaired, it's not a problem if the puncture is near the middle of the tread and the tyre hasn't been driven on a lot whilst low on pressure. I got it done at an independant place though, who are more likely to do it. Oddly though, this same place wouldn't fit normal tyres to my "runflat alloys" :|

Bridgstone tyres at cheap prices..... never found any for the runflats :P
Just the usualy online places to try, like blackcircles, tyreshopper, etc.

You may want to consider regular tyres though :thumbsup:
 
Officially the runflats should not be repaired, and I dont think that in BMW they will repair it.
They normally tell to change with a new one.

I have repaired runflat at a tire-shop in the past, no problem since then with the tyre.

it looses thgough its 'runflat' capability and any warranties
 
Within the approved tread area, run flats can be repaired. As a Goodyear associate, our warranty stipulates that a combination of patch and plug MUST be used. This will not void the warranty and the tire also retains it's original speed rating. You'll probably need to compare Bridgestone's warranty on their web site.
 
If you have run for 20 miles on your run flat without any pressure, does that mean that you can run for 20 miles less next time it fails if you have it repaired?
 
If you are looking for a cheap Bridgestone run flat, I have two rear Bridgstone 18" run flats with 6mm tread each, just looking for a home, as I changed to non run flats, and it seems a shame to just bin them, seriously if any one wants them, just let me know, as they are at my work and getting in my way, I even have a garage behind me who will fit them :thumbsup:

The visual tire inspection is obvisously the basic first step to ensure that no other damage (than the puncture) has occured. As a rule of thumb, the distance a run flat can go without air should be kept within 50 miles at speeds not exceeding 50 mph. The inspection will then determine if there is no discoloration or scrub damage of the inner liner or sidewall from heat build up or friction against wheel or road surface. A true professional tire servicing retailer is what the doctor ordered to give you a reliable diagnostic. Good luck :thumbsup:
 
When I changed the rfts on my One Series I sold them. But I still hated it and when I went to trade it in my local BMW stealer insisted I trade it in with rfts or they took £700 off trade in price. So I've kept my Z4s old rfts. Can recommend Goodyer F1 Asymmetrics as an alternative (18s).

Btw, has anyone tinkered with the pressures of non rfts compared to rfts? Witht he 1er I found an extra 0.2 bar made it feel just right but I haven't experimented with the Z4 yet.
 
I will try to get the tyre repaired before i buy a new one, although some of the garages i have spoken won't do the work for me..........

Thanks for all the comments though.

RustyZ4, you have a PM waiting for you!
 
Ok, here's a question...what is a GOOD tire gauge? I'm thinking of getting a dial gauge instead of a "stick" kind as the stick kind is marked off in 2 lb increments, and BMW lists 33 and 39 (front and rear) so you have to guess between.
