Well i have a set of 35X12.5X18 toyo m/t's and i was looking at upgrading the factory rims to something like the kmc rockstars. Im just curious what im going to need to go with as far as backspacing as i will most likely have to go with a 8.5 or 9" wide wheel. I have a 2" leveling kit but since the tires may come off for the winter, i may wait to put things on till spring and put it on along with a 6" lift. What are your suggestions for rim size.

 

You need to stay almost idential to the oem wheel size (7.5 inches wide with 5.5 inches of backspacing) to fit 35's at stock height on a 4x4.
