I was told I could go with 33's without lifting it. I want to get Nitto trail grappler 295/70/17 which are 33.3high and 11.6wide. The problem is I cant seem to get a definitive answer as to what kind of offset i need in the wheels. Can anybody tell me weather I need a positive or negative offset and how much of one I need to avoid any issues like rubbuing or hitting the control arm or inner fender?
You should be fine with those tires on a stock wheel actually. I had 35x12.5x17s on a stock wheel and stock suspension but because of the width of the tire they rubbed on the control arm at full turn (not much)
I have 1.75" wheel adapters now and because of the added width they rubbed on the lower fender slightly at as you turned.
Now with a 2" leveling kit theres no rubbing.
I think you can go up to a 305 (about 12" wide) without rubbing.
Factory backspacing is 6" and a 5.5" offset will do work. Factory wheels are 7.5" wide and most aftermarket are 8.5"
I think I just kinda glanced around that but if you have any other specific questions just ask.
