Considering that I'm more likely to damage things than do any good when
I take off a front tire and put in on the rear, I prefer to simply
leave it in place when the rear goes. I replace either tire when they
wear out and that's all.
And another thing, I doubt very much that it really matters to have
both tires match in make or model. So long as both tires are in decent
shape.

I don't get it, what are you going to "damage?" Have you ever gotten a flat
on the road? If so, moving a front tire to the rear and putting on a new
front tire is not any more difficult.

Again, the danger of having an old front tire is its more likely to blow
out. As Dave stated, which would you rather have, a front or rear blow out?
Be smart and *rotate* properly - when your rear tire wears out, put the NEW
TIRE on the FRONT, move the front tire to the rear and throw the old, worn
rear tire away. For mo
