I don't understand why everyone thinks they have to spend $2K to get 18" wheels when the stockers do just fine. I'm running a 35" tire on my stock aluminum rims and the 17" size offers far more choices in tires than the 18".
By the way, Kore (T-Rex) ran this way for a very long time, didn't they?
I am running the Mastercraft Courser CT 35x17x12. 50 and it's a D rated at 3000 lbs per tire (I think that's the maximum D rated tire, 3001 lbs would be an E rated tire). That's more weight than the GVWR so tha'ts plenty.
