So after 4 years of driving with the Goodyear Duratrac's, I've gone back to the land of true All Terrains with the BFG KO2's in 265/70-R17. Link to the original Duratrac thread, here.

On top of that, they weren't even on the truck for 24 hours before I got them dirty with a quick run to the desert for a little shooting. So far, so good with these new tires; they're much quieter than the duratracs, even when they were new.

I'll be keeping track of my mileage and will report back in a little while. I want to see if the mileage drop I got from the duratrac were because of the more aggressive tread or the size increase from stock.
