Okay so I just wanted to check with everyone if our cars wear tire more in the insides or the shop I go to for alignment is trash. I have a 2011 335is E92. The car is lowered on Bilstein B14 PSS.

Shop always gives me the sheet and the ratings are in green. Just wanted to confirm with everyone if maybe I should go at a different shop or it's normal for our cars to be like this.

Stock Camber for e92 cars is approx -1.5 plus or minus like .2

That is more likely caused by your toe than camber. Take a look at your toe.

I can also imagine a scenario where bad control arm bushings would allow extreme toe changes on acceleration, which could lead to that type of tire wear.

FYI I am at -1.7 rear camber and am not having uneven wear like that. It looks like you have the outer wear bars completely unworn yet?

My rear tires the inside will be smooth/no tread when the outside wear bar is like 3/4 gone. No threads showing anywhere on the tires. I’m running 1/8” rear toe in and have replaced almost all my rear Control Arms with M3 Arms and Manzo Rear toe Arms within the last year. So I feel my bushings are all good.

Keep in mind under hard acceleration the toe decreases momentarily, and this is also when most rear tire wear will occur. So when your accelerating hard your rear tires want to toe out and wear the inside tread the most. If you are tuned and modded this effect is worse because the forces towards toe out are stronger, and you should add more “toe in” on the rear to compensate.

Post up your rear toe from your alignment!

Okok this is reassuring. I noticed I did not save my last sheet... but I have one from my 1st alignement last year,


On a side note, you think I can do 200 km on this tire? I have to go get my tires then go to tire shop lol...

Turn the rear toe down to 0.10 each side, it really helps prolong tire life.

And that tire belongs in the trash, not on a 200 km trip unless you plan on having CAA on speed dial.

Will that in turn affect performance or? Because anyways even with even tire wear my tires will still wear as much right.

I do have CAA worst case lol. Wish me luck eh.

You should get that tire replaced somewhere close? metal is showing.

If not, hope you don’t injure anyone.

If you do, at least they’ll be able to find evidence for a negligence lawsuit.

As to the original question, somewhat already answered, yes, the factory specs (which is what any shop will use) has a smidgen of negative camber. But I suspect you are worsening the effect by lowering the car. And this is, AFAIK, not something that can be adjusted.

NEVER BE CHEAP WITH TIRES. If they're worn, replace them. Don't try to get "just one more month" out of them.

I wasn't being cheap the problem is I noticed them to late. I ordered my tires to pickup at the USA cross border so I had to pick them up first.
