Mein Auto: 750i
Premature Tire wear on rear tires 2012 750i

Hi All,

I am wondering if anyone else has had an issue similar to mine. Recently upon switching out my tires to winter tires, I noticed that both rear wheels on the inside (from the inside of the tire to about 2.5 inches) the tread had worn down to the steel. I have about 12000 miles or 21000km on the car. I made note of this and had the dealer ( Calgary BMW ) look at the tires during my most recent service. They told me that I had probably gone over a pothole and bent the suspension of the car and even maybe the frame the estimated cost of repair would be anywhere from $2000 x 2 for changing the suspension parts on each wheel and alignment and then if changing the subframe is needed then from $6000 to $10000. Of course, I do not believe this is plausible hat going over a pothole could cause this kind of damage. I suspect there is a suspension issue but they are saying they need to keep changing out parts until they solve the problem and of course, I am on the hook for all the costs because as they say "BMW does not sell bent cars". I am at a loss as to what I should do to further pursue the cause of this problem other than either paying them an exorbitant amount of money or trying to get a lawyer on the case to get their attention. IM hoping some of your can give me some advice on this.

ALso, I will say that both my front goodyear run flat excellence tires have already developed bubbles and I am also at a loss as I drove a 2008 BMW 750i through the same roads , driveway, etc and never had any issues even close to this with tires and wheels. Mine is a 2012 750i M sport with the technology package etc fully loaded and I paid $140000 for the car - I am very disappointed that my local dealer will not pursue the issue. Clearly if I had caused the problem I would own up to this and pay, but it leaves a very bitter taste in my mouth to pay this kind of money for a car and then have to pay another $15000 within 8 months to fix issues which I am certain i did not cause. I was very close to buying a bentley but went back to BMW because I had good service with them in the past with my 2008 750i - now I am regretting not stepping up getting the continental GT. Any advice on these issues would be greatly appreciated.

Thanks in advance!

Ritchie

Sound like the car needs an alignment. Inner tire wear is very common on BMWs. So much so that even tire wear is actually rare...

First, get a new dealer.
Second, get a 4-wheel alignment.

Regarding the tire bubbles, Goodyear has a tire warranty that comes with the tire. See if you are covered under that. Example - http://www.bimmerfest.com/forums/sho...d.php?t=557907

pathetic dealer. You likely have -2.2 camber in the rear, or large toe. An alignment will fix it, but the tires are screwed. Maybe with the before and after specs of the alignment, bmw will pay for the tires.

my new 2012 750li has almost 12k miles on it now and the rear tires won't last much longer. However, having said that, I'm very heavy on the gas off most stops so I expect the rear tires not to last all that long.

I have Eagle F1 Supercar RSA or whatever the summer tires are on my SRT8, and yea I get about the same amount of mileage on my rears. Well worth the price
