And it's all in degrees now. I had my wife's Envision when it was new because I didn't like the way it drove. AWD of course. It was within spec but not close enough for me. I had him fine tune it to real close to zero, front and back. One side was just in with the other side just a tick more and still in spec. We have about 50,000 miles on the original tires and I have never rotated them. no uneven wear, no cupping or chopping. They will make it through the winter with ease. It's just how it is.
