why are my tires wearing funny?

[Stanley Rockafella]

I noticed recently that my ALL STOCK e30 seems to be wearing it' s tires more on the inside, more than the outside. The seems to be the case for all 4 tires and the alignment is straight as an arrow too.

is this normal?

thanks in advance

BMW's come stock with more (-) camber than most cars. Normal. If you lower your car it will even be worse.

Could be your rear trailing arm bushings. They can be soft and cause the rear camber and toe to be off. Have you had the front aligned or are you assuming that it's good because it doesn't pull left or right?

It has nothing to do with rear toe and the trailing arms

BMW build all their cars for performance, therefore, they have 1-2 degrees more negative camber in the stock ride of their cars than most other companies. Even at stock ride height, my inside camber wear is definitely visible, especially on my rear tires. With a dropped ride height, it will be even worse. This is just restating what's already been said however

If it's really an issue for you: camber plates or offset subframe mounts can help you correct our unadjustable camber. Those cost $$$$$ though, but if you want a more run-flat look/wear pattern, those are your feasible options

If you ask me though; I kinda prefer the camber at a lowered height; not hellaflush mind you, but just stanced.

I think you right :)

or........ you can just swap your left and right tires from rim to rim when they start to get worn. You can also play with tire pressure somewhat to help.

just did this on my E36 vert.
