Based on your level pictures, camber doesn’t look to significant to me. BMWs seem to run a ton of negative camber - it’s obvious when looking at it without a reference.

I do think camber can cause excessive tire wear (I cal BS on 25 (!) degrees of camber not causing tire wear), but I doubt that’s the culprit in this case. I’d just take it to a shop and have a 4-wheel alignment done.

Also, am I understanding correctly that you have 50,000 miles on the original tires? If so, well done!
