Not sure if this applies to your issue or how far to the left you have to turn the steering wheel. you did mention your wheels are wearing unevenly but still.. felt I should share this.

I noticed a little drift towards the right fairly regularly on my newer '22. I took it in to have them check and they couldn't replicate it. The tech drove the car with me and explained that most roads have an angle dropping towards the right (passenger side) of around 4-8 degrees. It's how roads are designs so rain water is pulled off the road due to gravity.

I at first called bullshit. But he took me to a street that he said "this is the flattest road near our shop that has nearly 1-2 degrees slope. he let his hands off the steering wheel and it drove perfectly straight. no drifting to the right at all.

again, now sure how severe your alignment issue might be but I felt it important to share.
