I believe that someone posted a YouTube video here of the process for removing and replacing runflats. It looked pretty difficult, and I could not imagine how the wheels were not at least scratched by the process. I could easily see the crowbar-like metal that is pressed on the wheel bending it if too much pressure is applied.
As for vibration, there have been reports that some 19" and 20" tires will shift on certain wheels. I also think that these cars are incredibly sensitive to any imbalance (which is why my replica wheels caused so many problems). If you had the tires rebalanced after they were first put on, you probably eliminated the problem. Then again, road force (high speed) balancing on a Hunter (or similar quality machine) is really the only way to guarantee a true balance.

Run-flats are crap. Unless you get a tiny puncture they won't work properly. If you have an explosion like this:
this is what happens. I also had an explosion on my nct-5 and after rolling for a maximum of 7 km with speeds not more than 60km/h the result was the same as in that video.
Also indeed damage can occur when dismounting the RFs. I am also afraid when i'll change mine in spring. After that i don't even want to hear about RFs.

You got a real nice car that im sure you paid good money for.
And then you go to costco to mess with Runflats?
I find that dealers are rather not very expensive to do the labor on tires. I have either had tire rack ship the to the dealer. They know the car and rims better than anyone!
Im saving money and getting the job done right.

Two things for the OP.
1 DiId you watch Costco mount your tires? I think their equipment mounts from the outside of the rim, not the inside, so it would be tough for them to do the damage. I'd go watch them do a set of someone else's tires and see if they are doing something odd.
2 Costco guarantees everything and should replace the wheel IF they damaged it. You have not gone high enough up the chain if you didn't get your money back and a new wheel.

A mate of mine has a tyre fitting company close to my local BMW dealer. He does all
their cars. He had to have new equipment to properly remove and fit Runflats! So yes it is possible that Costco bust your rim.

If the installation is difficult and the tire guy/gal is inexperienced or just plain stupid they will take the rim and flip it over on the machine. Which then in turn will scratch the crap out of the face. I saw this happen more than once. They will then hide the scratched rim(s) on the passanger side of the car so the driver will not notice until later and think that they hit a curb.

Further to my earlier post:
I now have two brand new (hopefully round) wheels on the back of my car, courtesy of the Dealers.
I also have a puncture!!! A 4 inch nail.
The RPA didn't alarm because the tyre wasn't losing pressure. It's frightening to think of the speeds I have been doing recently, probably with the nail in the tyre.
Being of a miserable disposition, I didn't want to pay Dealer prices, and also I didn't want a new RFT as I want to go to "proper" tyres. The Dealer wanted GBP195 for one tyre (a Dunlop) and my local Tyre shop is looking for GBP89 for a Pirelli PZero Rosso - a tyre that I have had experience of, and would be happy to fit.
So - a similar price for one RFT or two proper tyres. No contest I think, particularly as the other RFT has only 5mm left on the tread. All I need now is a chocolate-button spare wheel!

JMK BMW replaced 4 RFT's in about 1hr 45 min. without any problems. If you think back how many people posted on this board about having there Dunlop's replaced because of noise by there BMW dealer and to the best of my recollection nobody mentioned any thing about damaged rims.

My dealer did scratch my rims as they do not ahve the proper equipmment. I found this out a bit too late. I finally go them to tell me what they do with the Uber expensive cars as I figured a scrathed weel wasn't goint to fly on a 760 or Z8... anyway they send those jobs out to a another local shop. Come to find out they do the wheel and tire work for the ferrires and the like around here. So I now will go directly to the specialy shop for wheel/tire work and bypass the dealer.
