I have been searching for a while now and I am ready to order so I want to make sure it is right. I am getting the pro comp 6 inch lift with 20 inch chrome rockstars. My questions are about wheel width and tire sizes. Which option do I need? Will the 10 inch wide weels fit and will 35/13.50/20 fit. I want to go as big as possible without rubbing issues.

option 1
20x10, 6 on 5.5 / Bolt Pattern
Back Spacing = 4.56 in.
Offset = -24 mm.
Hub Bore = 108
Finish = Chrome

option 2
20x10, 6 on 5.5 / Bolt Pattern
Back Spacing = 4.56 in.
Offset = -24 mm.
Hub Bore = 78.1
Finish = Chrome

option 3
20x8.5, 6 on 5.5 / Bolt Pattern
Back Spacing = 5.14 in.
Offset = 10 mm.
Hub Bore = 108
Finish = Chrome

option 4
20x8.5, 6 on 5.5 / Bolt Pattern
Back Spacing = 5.14 in.
Offset = 10 mm.
Hub Bore = 78.1
Finish = Chrome

These are the only one I think you might have a chance of not rubbing with, (and have a closer hub size), but with a 35x12.5" tire.

The smaller the backspacing, the more they will stick out and cause the tire to rub the pinch-weld, mud flaps, and the wheel liner. I know a guy with a PC 6", 9" width wheels and 12.5 width tires that had to cut off a little of his pinch weld. With 10" 4.5 b.s and 13.5" width tires you'd be out 1.5" worse than him with his Moto Metal 951 and BFG MT KM. [His rims were 17s, but wheel diameter doesn't matter much at all when it comes to backspacing and tire clearance ... tire diameter does and width, but mostly wheel backspacing and wheel width].
