Thanks a lot guys for the input.

Another question. With the stock carb on the 20r, I think I remember reading I should be getting roughly 90hp. Is that adequate to turn the larger tires, even if I go with the narrower version?

Many years ago, I had a 2wd Datsun (yep before Nissan) pickup. I put the wide tires on the rear which helped a lot in the mud but took a sever toll on power.

While I know there is no perfect answer, what do ya'll think is the best compromise?

Don't miss the forest for the trees.
