Welcome to the Fam Karla
I too will be purchasing new tires. I'm getting BFG Mud Terrains in 245/75/16. These were the tires and sizes used for the Longitude "Drive-Around-The-World" Expedition on the Series II Discoveries. You'll find that a lot of RoverHeads are using these tires as well as the All-Terrains. If you're willing to sacrifice Road Noise and just a bit of a bumpy ride, the MTs will do.....if you dont want to sacrifice City-Drive Quality but still require EXCELLENT off-road performance, the All-Terrains are the way to go.
Hope thi helped some.
