Fat_man,
I like the wider rear track as well, but I had heard in the past that the narrower rear track is done so that you don't get hung up. If your front end makes it through, then the rear will too??
I know that this is very true of mountain bikes (obviously not the same, 2 wheels vs. 4, stability, all that) where they tell you to have the wider and more aggressive tire on the front instead of on the rear where you'd normally think it would do more good.
I don't know this for a fact, but am throwing it out there for consideration and possible correction by someone who does know. I've never quite understood this argument, as some dually setups obviously have a wider rear width than front.
Does anyone know if this narrower rear setup is for tracking purposes, or exactly why does it exist?
Thanks in advance for any information!
