Well I 'm just getting ready for the lift, I've got wheels on the way 17 x 8 /w 4.5 inch back spacing.. That should give me enough room for a tire 11 inches wide or so without rubbing the UCA.. right? 285/70-17 is pretty close to a 33 so that will do it.. I just don't want to stuff the wheel up into a small tire well if I hit somthing hard and trash it.. (the tire) Thats why I was wanting to try and get a few extra inches in there.. Maybe if I were to just use a top spacer in the front on top of new springs I could squeeze in 285's?? probably be about 4-4.5 inches of lift..
