I agree, should have been changed a while ago but i'm dialing in alignment numbers. R & D to see what is capable/possible with differing variations of numbers. Changing the tire before now would have produced a smaller yield of information ?Excellent milage but that tyre should, in my opinion, have been changed some time ago!
I had mine set to 0 and had perfectly even wear. YMMV (literally)
That sucks...I’ve called around to a few shops and it seems like most alignment shops won’t touch the car, or can’t manually adjust from factory settings.
