Size of ring and pinion --- The 4.88 is smaller than 4.56.

With 35s, and 4.56 I can still run 65 highway with about 2500 rpm.

I don't have a link handy but you might do a google search for tire size and gear chart.

There is a band where you need to match tire and gear size to keep rpm at an optimum.

What is your definition of "extended" road trips? Is it going to be to trailered to the trail or driven from home to the trail?
