:tu: You're right, it will be close. Probably only a couple MPH off with stock tire size. If you go oversize, like most do, it's something to consider. My factory size is 275/70/18 and I'm running 35x12.5x18 and I was off almost 8mph.
I'm just sayin bigger wheels generally lead to bigger tires, that's all.

Thanks it looks like standard 65 series 20's only add an inch to the overall diameter on standard on-off road tires with a max of 34.1 inches. I was looking at the Good Year Dura Trac Commercial. Looks like a quality on off road tire with a decent tread depth.
