I agree for the most part there is no definitive answer because the variables are so great.

For instance if you want the ride height unchanged but want a larger rim then the rubber will be a rubber band around the thing. VV you could go with a 15" wheel with larger rubber like we used to do back in the day on lifted trucks.

Even the clearance for turning you asked about is different from rig to rig. Some stock will rub on the sway bars (my passenger side does) and some don't. Some can stuff 37's under there with no rubbing at all.

I am in the same boat trying to figure answers out. I would like 37's but I need to figure out the backspacing on the wheels I get so they can be pushed out a little so they don't rub. Also I need to find out if I will still fit in the garage since I only have 2-3 inches from the roof rack.

Keep searching around, you have to piece bits and pieces together from many various threads. Check mostly the tech sections of the different forums.
