If you are planning on using the factory 18" rims and keeping the same size tire then there are only 2 tire choices available.. the Continentals it comes with or the GoodYear SRA's that come on the Titan.. if you have the Off-Road Package with the 17's then you may have a few more choices but not much..
I do think BF Goodrich makes the BFG AT KO 18" in a slightly wider but lower low-profile AT tire.
If you replace the rims with bigger or smaller diameter you may open up a new realm of possibilities.
