I traded in the 2011 BMW for the 2012 A6. I have had it for 6 months, 10K in mileage and can tell you it was well worth it. The all wheel drive is by far superior to the BMW. Also Transmission and suspension in the A6 far exceeds performance of the BMW. People can argue wheels all day long on this forum but the simple truth is the BMW as seen better days.

What everyone seems to be missing is that it is not a simple case of changing tires. It has to do with a combination of tires, wheels and the suspension system. For a vehicle to constantly bottom out over almost every bump is not normal for any vehicle. I have owned many cars with lower profile tires and have never had to replace any wheels or tires as a result of the size of the wheel and tire sidewall, nor did the vehicle botton out. Someone miscalculated something when it came to the suspension.
Go get an Audi and enjoy driving again.

I'm not gonna argue the point, but I'll simply say this.
Do a Google on "XXX alloy wheel damage", where XXX is BMW, Audi, Nissan, etc. and you will find every manufacturer shows up with wheel damage.
I'm not here to defend BMW nor accuse any other manufacturer of defects, nor praise them. I'm just saying that the incidence of damage is directly correlated to the diameter of the wheel as it increases in size.
If you want the bling of 18, 19 or larger wheel sizes, get ready to pay extra.

It is absolutely true that the lower the profile tire and the stiffer the sidewall, the less "give" you are going to have, and the more problems you will have.
But, I am comparing apples to apples here: a 2011 BMW 535xi with the standard 18" wheels and 45 profile tires against other cars with tires of similar size and profile.
I have driven over 500,000 miles in cars with 17" and 18" 45 profile tires over all kinds of roads on three continents. And, as noted in my post, I have now tested a sampling of such cars over the same pothole at the same speed.
ONLY the 2011 535xi exhibited this problem. I believe that is a combination of the very stiff RFT tires and a suspension design that is not suitable for our potholed American roads. You would probably never encounter this problem in Germany. But our roads are much worse than theirs.
This would not stop me from driving this car in an urban area, but we no longer trust where it could leave us stranded a long way from civilization.
I would love to hear from anyone who has a 2011 5 series and who has replaced the RFTs with conventional tires. Does this solve the problem? Does the suspension still crash? Have you had any tire or wheel damage since making the change?
#100 of 136 5 blown tires since Sept 2011
Apr 01, 2012 (9:08 pm)
I leased a 2011 535xi with the M Sport package. To date, I have blown out 5 tires due to driving over pot holes. I have never seen anything like this, and the previous post about this being exclusive to this model BMW is accurate. It's a combination of the suspension, rim design and tire. The car feels like it is about to break into two pieces and as a result the tires blow or bubble.
BMW has replaced all the tires at no cost. This issue, along with the slow tip in at throttle and I am hugely disappointed in the car. Working to return it to BMW this week.

Either you purchased the wheel & tire insurance or you must have the most understanding and sympathetic BMW dealer in the country!

Apr 02, 2012 (12:11 pm)
What type of rims and tires do you have? How big were the potholes? Where do you live? Did the tires blow up?

The M sport package includes 19" wheels with lower profile tires, so I can readily understand why you would be having even more problems than I.
How did you get BMW to pay attention to you? They told me that I had to go through my dealer. So, I got the sympathetic service manager at the dealer to contact BMW on my behalf.
Through the service manager intermediary, BMW has just blown me off. Told me that they are are not aware of any problem with F10 tires, wheels or suspension.
Just for good measure, they informed me that replacing the RFTs with conventional all season tires would void my warrantee on anything relating to wheels, suspension or steering.

Consumer Reports complained about the (non sport) 535i they tested crashing over sharp bumps so hard that it sent shudders through the entire car.
Car and Driver had six bent rims and two blown tires in 40,000 miles on their 550. They blamed wheels that were too soft. I think that it has more to do with the suspension design combined with the very stiff RFT tires. Probably fine for German roads, but not for the U.S.
#105 of 136 Other vehicle wheel problem
Apr 06, 2012 (2:25 pm)
I've not had any problems yet with my BMW (535GT - just turning 1-year old), and the only other vehicle I ever had to replace a wheel on was an Audi A6 - one bent so much on the rim it wouldn't hold air, the other enough so it couldn't be made not to vibrate at speed. I still contend that the lower the profile tire you go with, the more issues you will have, and anyone using the 20-22" wheels on any of these cars is just asking for major hassles. Maybe it's an issue with the RFT being stiffer - this may transmit more force to the wheel since it doesn't deflect as much as a conventional tire; but, the lower the profile, the stiffer it has to be, just making the problem worse. My vehicle is a tool - I care about how it operates, not so much on how it looks. I'm not out to impress anyone, and I can't see it from the outside when using the thing as a transportation tool. As long as it's comfortable, and does what I ask of it, I could care less about whether the wheel fills the wheelwell, and I'll take the more resilient, higher profile tire.
If you must have the bling, heed BMW's warnings, and take your chances. They install 18" as stock for a reason. Now, if your need includes track time or slalom, that's a different issue, and you don't normally find potholes at the track!
