Tim, I don't understand the logic of this. If you are wearing out
your rear tire twice as fast, why put a half used tire on the rear?
Would you not have to replace it twice as quickly as if you put the
new tire on the rear? Not trying to be a wise guy, just trying to
understand what you are saying.

Ah, that's pretty simple. As was pointed out in the post to whch I was
responding, the front tire basically never wears out but eventually
fails from aging- spossibly with a sidewall blowout or something else
catstrophic. By swapping the front tire onto the back and putting the
new rubber up front, you eliminate this problem.
