These setups on otherwise stock Rubicons will rub on the street when weighted down with a full set of passengers, even if they're kids. Been there, did that for more than 5k miles before I was finally able to afford a lift.
I'm running 37 X 12.50 Copper ST Maxx on a 17 X 9 rim with 4.25 backspacing and with Artec inner fender liners and gutted fenders with the AAL fender light and bracket I need 1"bump stops in the rear to keep the tire out of the fender at full stuff. I had gutted the fenders before installing the rims and tires. This works great for around town and could handle some decent trails. I wouldn't want to leave it like this long term and i plan on finishing up the suspension lift when i figure out what springs and shocks
