Rear tire wear 2005 X5

Good mech. shop can dial out that crazy negative camber to 0.05* it almost straight up like the front wheels... Run your tire at 40psi to help the inner wear..
I ran my 20's with 315 wide and have no issue after 30k miles.

Mate i had exactly the same problem a little while back on my 19's, however not quite as extreme as yours. I also have an 05'. Luckily i needed new rubber anyway ( went with Bridgestone dueller HP sports which im really happy with just quietly ).
Anyway, my alignment was quite a way out and i had the camber reduced to negative 1, this seemed to work without pushing out the toe.
Its only been a few months but i do a fair bit of driving and wear is pretty even at the moment, im going back to the alignment shop in a month or so for a check up to see if everything has stayed reasonably in spec so ill let you know. Even with negative camber, from research i did on this forum it seems it may wear a little prematurely but not as bad as your photos suggest.
I'd definitely check out your control arms and bushings.
I should mention that when i had this problem that i also got alot of help and advice from forum members so a big thank you guys. Good luck

Wow!!
My wife's X5 had the same problem. The camber? whatever, my dealer guy said it was -2.4 and they adjusted it to -1.5 for both. and everything is going down evenly.

When i bought my 02' 4.6 it had a BRAND NEW pair of rears on it (they still had the titties on them). First thing we did was take it on a 3k mile road trip, and when we got back they looked just like yours. I was so ticked off, ordered a new set of rears from tirerack and had them drop shipped to my favorite tire shop. They checked the alignment and it was "within bmw tolerance" which was something like -2.7 on each side. I had them take every ounce of negative camber out of the rear to get it as close to 0.00 as possible. They got me to -.5 and -.7 and thats mechanically the limit of the rearend on my X5. That set of rears ran me almost 50k before the whole thing needed new rubber again.

btw, i run max pressure in my tires. And I kind of cheated a little at the end of that last sets life span. I over inflated by about 10lbs to make the tire dome and get it off the shoulder of the tire. Good bad.. whatever.. it got me about 5k more miles before i just didn't feel comfortable driving on worn rubber any more.

He's right about dialing out the negative camber. BMW designed the rears so the vehicle would not rollover. When I had my new Vredestein's installed I had the rears dialed out so the wear on the inside would be minimum.
