I think the best tires are for 18" wheels, I would rather keep my stock wheels too, but they dont have much of a selection in E rated 35X12.50X17s. I looked at 35X12.50X17 tires from Pro Comp, Dick Cepek, and Toyo A/Ts and there all D rated. In 18" tires they have the 285/75/18(35X11.50) Toyos A/T or M/T and there both E rated. You can find 18" wheels on the Discount Tire Direct website, they have Ballistic Off Road and MB Motoring wheels with 6" of backspacing(25mm offset) too.
