VERY Troubling Story From Bimmerfest...

my question for the bimmer guy is why in hell is there so much wheel weights on the wheel?
this kind of points of something being way off. usually tire balance issues don't need so much weight unless the wheel is bent or out of round. perhaps it was cast improperly and not round?

that's crazy.
A wheel might do something like that at 100,000 miles but brand new?
Is this a standard wheel on the BMW or aftermarket the guy put on himself?
I would definitely upgrade to a 3 piece wheel after that.

this makes me feel satisfied to have OEM wheels.
honestly, I would have never expected to see a wheel fail in such a violent manner.
the wheel balance weights are an interesting thing to being up. while the wheel may have "balanced" in the way of rotation on the high speed balance machine, that much weight may have been applying great stresses to the wheel both radially and axially (ie. around the barrel and across the barrel). I would imagine these stresses would be magnified at highway speeds.
nevertheless, this should be a non issue. 99.99% of OEM wheels are cast, and they never fail like this. I know for a fact that lazy wheel and tire shops in town simply add new wheel weights to existing ones when they do their balancing. I would bet hundreds of wheels with hundreds of thousands of miles have this many or more wheel weights on them than this.
for this to have happened twice to the same wheel manufacturer: yikes. this proves the value in having a team of engineers working diligently to ensure that manufacturing processes are not only safe and good in theory, but also in practice.

Just...WOW!
I like the looks of some Sevas wheels and had considered them an option. They're now off my list.
I'd like to hear D2's response and if he plans on keeping them [Sevas] in his lineup.
TX...thanks for the thread man.

I didn't read it all, but is this person sure the wheel failed and then the tire failed? What was the order of events here? Anyway, this is a good article you should all read.

I had a set of Sevas on one car and still have a set on my wife's car. I haven't had any problems but two examples of cracked wheels concerns me a little. I'm going to change the wheels eventually and hope everything is okay until then. I don't think there is anything to panic about but Sevas does make lightweight cast wheels and they are made in China. With all the publicity over poorly mad products coming from Chine these days, I believe there is some real concern. Darn it, the new forged wheels I just bought were made in China too. Oh well!

I was advised that all precautionary methods are being taken, any and all damaged wheels are being tested, to find the source of this issue.
That being said we will not be selling any of their 1pc wheels until this issue has been resolved.
