Hmmm. Regarding your tire size problem:
You can change the effective diameter a fair amount by changing the tire
inflation pressure. Especially if you're running oversize tires like the
10.5x31-15s I have on.
You can get a close approximation to the rolling diameter by measuring the
radius from wheel center to the ground (not center to top, or center to
front or back). Get this to be equal, and you should be okay.
I understand the NASCAR folks worry alot more about this, and have to figure
in not only what the pressure will change to as it heats up, but the
increase in tire diameter due to centripetal forces. On the other hand,
they're not running in 4WD, and they're going twice as fast as you'll ever
go in a Dakota (in the wintertime, anyway).
