I'm considering the same thing only not sure whether to go with the body lift or the suspension lift. seems the suspension lift may be easier. thinking about going with 31x10.5x15's. Just looking to get the truck up a little more, as the stock setup makes it feel like you're driving a car.
My factory build sheet for my 2000 Dakota SLT 4X4 shows 15X 8" wide factory rims with 31X10.5r15 is a factory equipment size. I am looking at going a size bigger myself. To the 32X11.5R15. with a Torsion key twist to (almost) level.
I have the same question for my 2001. Has a 3" bodylift. going to need new tires sooner than later. Have the 16" wheels, wondering what would look good on, not really trying to put 33s or anything like that, right now have 265/70 on there. Trying to keep it a little modest and not going for the outrageous
