More than likely you will need to add a small (1" - 2") body lift to clear that size tire (33in. Equilv.)
When you order the SL talk to SLR about that tire size and ask about the smallest BL you can get to clear the tires.
If you want to avoid the BL then you need to stick with a 32" (265/75/16) tire.
And if you want something different tire wise, I'd seriously consider the Toyo Open Country M/T as an alternative to the Nitto.
