alignment wrong?

I agree the toe is probably the issue. All tires are not created equally. You need to align it so the tires wear good, regardless of specs. Also, the included angle on that left side looks spooky. If it's right, I would suspect a possible bent spindle. That coupled with the low caster on the left, throws up a red flag. Lastly, get out and cross the front tires right to left. I promise the pull will change. It should be pulling to the left. That alignment needs to be done over, IMO.
