Hi guys I'm sure you are tired of people asking but I'm a little confused.I think rough country says you can run 4.5 bs with their 4" and 33's other lifts say more like 3.75 or 4. I am putting on a 3.5" rancho lift and 285/75/16 so will 4.5 bs be alright? I can't seem to find 16" wheels with less backspacing lots of selection in 15" though.Thanks.

lift height has little to do with BS. its more about wheel width. a 33x10.5 will be ok with 4.5" bs. a 33x12.5 will be better with 3.75-4" of bs

every jeep is different, and thats in the middle, its hard to say. i'd think you'd be ok, but you may have to add a washer or two to your steering stops to eliminate rubbing at full lock

I've got 16x8" wheels with 4.5" backspace. I had 305/70R16 (33x12) Toyo AT's on them with no rubbing (4" suspension lift). I now have the same size Goodyear MTR's on them and have very slight rubbing on the lower control arms at full lock. Haven't put a washer behind the stops yet. You shouldn't have a problem with the 285's. If you haven't already got the wheels, I would advise you to go with 15" wheels...tires are a lot less expensive and there's a better selection.
