I think I saw you mentioned that you have 275/65/20 KO2's earlier, and some have mentioned the need to add a spacer. Did you end up adding a spacer to fit these without any rubbing on the UCA? If so, what size spacer? I just bought my 08 (same color), and am looking at tires now....
Just removed the mudflaps up front and nothing else. The KO2s in this size run smaller than other tires in the same size, so I didn't have the clearance issues that others may have faced with a tire like the Falken AT3W. In reverse at absolute full lock going over a bump, it might occasionally kiss the plastic up front, but it's so slight there aren't even marks in the plastic where it hits. Even wheeling it doesn't hit anywhere, but I'd say this is the absolute biggest tire you can put on without some mods to the plastic or more.
