Could someone tell me the stock rim specs for a 2016 20'' rim. Some have said the offset is +44 others have said +31 with 5.97 backset? Im looking at a different rim that is 20x9 with +18 and 5.71 backset. I will putting on BFG KM3's 35x12.50R20 and I'm looking into how much clearance I will have. I will be adding a lift, I just dont know how much I need or if I can get away with nice leveling kit with UCA's with a diff drop.
