Didn't you just replace everything in the rear / front suspension Spencer? Sometimes worn suspension components make things wear uneven, but for you I don't think that's the case.

Since the rears are really the problem, I'm not sure here. Do you have your current alignment specs? Are you wearing the tires evenly in the rear or do you have a lot of toe (BMW specs too much toe in the rear from the factory alignment specs and tends to wear the inner edges quicker)

How often do you change ride heights? Alignment should be performed every time you reset normal ride height.


Have you replaced the bushings on the subframe as well? Those could give some play in the rear.


What is the load rating on the tires? Although others have had good luck maybe they aren't load rated enough to handle, I'm not sure I never ran those tires. I know any tire I buy for the X I make sure it is "XL" load rated for good reason.



Just brainstorming man sorry to hear that, on the plus side I have had great luck with Toyo Proxes STII and other members love those Conti DWS tires!

EDIT: Just read your post, not your suspension then I believe. I'd say defective batch of at least 2 tires (the rears), out of round or old stock maybe, hope they have warranty!
