If anyone is inerested I was able to fit Toyo's Open Country tires on the OEM 18's. 265/75/18 for reference. Had to do a little clad trimming.
Gained 2.75" in rear and right at 2" up front with tortion bar cranked all the way.
Ride is much better. I think I was bottoming out w/ original springs. Also the tires help the ride. Coolest aspect is the lowest point (rear diff) 10.25". Pretty hard to beat for a mod that took one full day and less than $200.
