Tks for this input. I new some of it but needed conformation especially for my boyFor a daily driver I would not run anything bigger then a 35x12.5 tire. Back spacing of 4.5" and a 8.5" or 9" wide wheel would be recommended. 37's need so many upgrades to run reliable. But since you have to have 37's 12.5" wide with a 3.5 bs wheel it typically what people run. Steering becomes an issue on the really wide tires since you don't have full width axles. JKU's generally will bend the rear axle flanges on 37"+ tires. You also tend to go thru ball joints, unit bearings, and brakes.
