I say that some tires can tolerate it, but think for a moment....You are saying no to rotating tires? I go front back @10k miles. I replace due to age, cracks, weathered before wear mostly in CO. MN wear, extreme age. (Over 15 yrs) but still fine.
If you rotate and the tires actually DO wear evenly, then in a while you have 4 tires to replace all at the same time.
That's a marketing ploy - one to which I didn't comply even though the suppliers wanted me to post a 5-point or 4-point tire rotation poster for my clients to see.
It generates a lot of business - and a lot of busy work - for a fee for the shops at the same time.
IF you have a certified reason to move a tire from one position to another, I suggest that you start with new tires at the rear and as the previous set of front tires wear out, then ONE TIME - move the good rears to the front and put the new pair on the rear.
For a singular reason, I say that and we can discuss it later if you wanna.
