3.5" lift r18 backspacing
 

Hello. New girl here. I have a 2016 jku with 3 5" rough country lift suspension kit with control arm. I need to know what backspacing and offset I can go with as I need new 18" rims for my 35 12.5

You should be fine with 3.5' or 4.5' of backspacing.
with 4.5 the tires will stick out an extra inch.
In some areas the cops may ticket you for having your wheels stick out too much.
