Uneven rear tire wear common?
 
2 Attachment(s)
Bought my 08 w 11k miles and during the wheel swap I noticed uneven rear tire wear - these tires are almost shot on the INSIDE. Is this common or were the wheels mis-aligned at the factory? Thanks in advance for anyones replies.

Run-Flats?

Yep - usual issues! Get rid, save 50% and more life in each tyre and better ride!

I wouldn't call it normal. It's more of a tire pressure issue. I got great life out of my tires.......only changed the rears and that was around 35k if I remember correctly. Turned the car in at 39k..........Phil

It is normal but preventable. The camber on the 6ers needs to be adjusted to factory specs, quite often(6months-year) or you'll go through tires like water...just another preventive maintenance thing.

I would get an alignment and also check the condition of the bushings in the rear suspension. When bushings start to wear you can bad toe-out during acceleration which will give you a narrow band of tire wear like in your pics.

Dealer says I need a $350 " dynamic balancing " ??????

I know this is an old thread, but thought I would add: I've replaced my rear Bridgestone Potenza Run Flat's 3 times in the last 2 years, getting almost exactly 8,000 miles out of each set. Classic BMW in Dallas performed the alignment when the tires were changed. I took it to a non-BMW german service garage, and they said the camber was adjusted correctly, but the toe was drastically out and was causing the tires to wear one inch of the inside down to the threads while the rest of the tread remained. He corrected the toe and said he feels confident that he's fixed the tire wear problem. We're going to check it in 3,000 miles.
I called Classic BMW who told me that the factory setting for the toe is aggressive for good handling and that's the way they set it. I was told "Some M cars are having their tires replaced every 7,000 miles". Well, I suppose that's great for Classic BMW's tire sales. I made my tire wear concerns known, and they still set it to max tread wear. I'll try to come back and update whether the new alignment cures my tire wear problem.

I also have had this issue = was it solved ??

FredoinSF 10-11-2015 07:11 PM

There is nothing to solve. it's the cost of the power and handling that comes with this car. It eats through tires. You could buy non directional tire and flip them.

The stock alignment causes the inner to wear heavily. If you want to flatten out the rear tires you would need to purchase and install a camber kit, the stock setup won't get you there. See below:

Hello everyone, I was reading through some of trends for causing a worn inner tire. I understand that some of our vehicles might have a bit more aggressive alignment due to our dynamic Drive, but when the camber us so bad that it cracks the rim several time it hits a bump it's way to much.

So my question is, do anyone here know how to Adjust a negative camber on a 6 series w/pictures or video (preferably). I'm going on my third rim and I don't want it to go any further.

Thanks.

Gentlemen, I have two 650i, a 2008 and a 2010 , both had alignment set at 0 camber and 0 toe in , front and rear, 37 psi inflation, smooth as silk and only minor flat ware, front and rear . I use GATTOS in Melbourne Fl, see Mike Green 321-421-6600 ,excellent service. all the best OLE MAN.

The issue is not your alignment, it's your rims. What wheels are you running? If they are the stock 645 rims, they were so bad, there was a class action about them (sorry you're too late).

I had 3 bad rims and changed to M series wheels and no more issues.

The negative camber in the rear is to get better contact on hard cornering. You can buy a kit to change it but that won't stop your wheels from breaking.

BMW645CA 04-28-2016 05:56 PM

It's only the right rear rim that was cracking onn the inner side. The other wheel seems to be working just find. The wheels that I'm running now are also M series. So hopefully that helps abit.

HerbP 04-28-2016 07:58 PM

I think that the cracking rim problem was from a combination of a poor wheel, & the RFT tires stressing them to much. The ride with a standard tire, is a world of difference.
