try a microfiber cloth and see if it comes off.

looks like they nicked that spoke too.

Not unusual at all.

About two years ago, I had a rear tire replaced and the tire shop nicked the wheel of my new 1er.

Yep, that's definitely from a tire machine. Looks like the tire wasn't all the way in the drop center creating lots of tension around the bead and machine. Depends on the kind of machine they use but generally that is what that kind of mark on a wheel is from, or something scratching the wheel while it is spinning while being mounted.

You try to rub some car wax on it?

Just put some of that on a microfiber towel and rub it on the area. It works pretty well at getting stuck on gunk, off. I've used it on my fenders when there was rubber stuck on them from rubbing and it worked flawlessly.

sadley he is correct, i always bring my rims to high end shops that do this kind of work. Normal tire shops normally dont have the touch less machince to protect the rim.

Same thing happened to me today while changing from the Dunlop run-flats to Michelin A/S 3's. However, the shop manager brought it to my attention, made immediate arrangements to repair the damage and will provide a loaner. Things happen, but when someone takes responsibility and corrects the mistake, there is no problem.

This happens all the time. Tire shops are no better than Jiffy Lube and trash a lot of wheels just being careless and working too fast.

It could be, but it's highly unlikely from my experience. If the wheel had a defect where it leaked from the bead, this would have been apparent from the beginning when the car was new still. Sometimes gunk and debris can cause a tire to not seal properly. If the bead is not really clean, the seal won't be good enough for the tire to hold air without leaking.

Another thought on rim damage. Replacing a run-flat with a run-flat has the same potential to damage the wheels as replacing a run-flat with a regular tire. The damage occurs because it is so difficult to remove a run-flat tire. I don't understand why BMW is so enamored with run-flats. I find it interesting that the new M235i now comes with Michelin's PSS. I wonder if customer sentiment influenced this move. I also wonder how much the PSS's have contributed to the positive reviews of the M235i. Some one needs to compare a 135i or 135is with PSS's to a M235i.

That looks like bead sealer on the edge of the rim. I hate that shit. IMHO, there is never a need for it, unless the rim is badly pitted on the bead. I have been doing tires for 15 years in the highest salt use region in the world, and have only had to use bead sealer twice. The bead of the rim and the bead of the tire both have to be spotless.

If they put sealer on the bead and it still leaks, that is probably not the problem. I would be checking the TPMS sensors for a leak. Get a spray bottle, put some dishsoap in it and fill with water. Spray the bead and sensor down completely soaking it. The leak should show itself pretty easily with a big mound of bubbles. If you find it is leaking from the bead still, you may have a cut on the bead of the tire, caused by bad install or removal.

BMW's love of runflats is simple. Their present target buyer (who is definitely not most of us here) loves the idea of never again changing a flat tire. They also get to omit the spare and the tools, less money, less weight. BMW started early, and is very commited, but more and more manufacturers are going there.

Without getting into an argument as to whether the M235 is a "true M", their M cars have never had runflats, I believe. Different target buyer.

You are right about BMW's target customer not being us. It appears that BMW would prefer selling cars to the masses rather than enthusiasts. They will accept whatever BMW is pushing just to have a Roundel on the hood. I will not buy another car where I have to change tires to get real tires and then buy a spare tire kit in case I get a flat. My 135i was transformed when I put Michelin Pilot Sport A/S 3's on last week. BMW should allow a customer who factory orders their car to have a choice of tires.

Cudo's to the dealer.

I just had my RFT's replaced with the A/S 3's as well. Great improvement.

Wow, I would think there is a cut in the bead of the tire. Won't know for sure what is going on until the tire is pulled off the rim. I would get them to take the tire off and show you what is going on.

The tire is supposed to seal on the bottom edge of the bead. There should not be any pressurised air getting to the sidewall of the bead like that.
