Do these initial numbers look like it would have caused the wear, specifically the toe? I left out caster because it was right in the middle of spec, and didn't change after the alignment.

First 7000 miles with:

Front Camber: -0.25, -0.21
Rear Camber: -1.02, -1.29

Front Toe: 0.20, 0.20 !!!!!
Rear Toe: 0.22, 0.15 !!!!

After alignment:

Front Camber: -0.29, -0.53
Rear Camber: -1.03, -1.28

Front Toe: 0.02, 0.00
Rear Toe: 0.02, 0.03

The front toe was way out. Would nearly double the max spec of toe (total +0.40 front and +0.37 rear) cause that kind of wear? If so, I'll gladly take back my view on the tires.
