Are those toe specs?
Toe will not cause tire wear unless way out of wack and then you'll know because the steering wheel will be off by a half a turn. If you drive down the freeway and the car goes straight by itself and the steering wheel is level it is fine. Most shops give a 90 day on there alignments so it might be worth calling the original shop to see if they will hang the heads just to make sure everything is up to par?
