With a 20x12 43 offset, Thats plus 13 either way. The inside has room and it should make the outside flush or just under. I may just go wuth 11.5 43 offset to be safe. With that i can run a 345/30/20 cup 2 O.D. is 28.2 just under stock. They are on the narrow side of just 12.7 tread width. The wheel width minimum spec is 11.5.
