Lol well see I'm a cheapazz, and think that tires are way overpriced, so I stick to military surplus. I had 37" HMMWV tires on my last truck, but want to go bigger for the next truck and I'm leaning toward the 46" XMLs used on APCs and a couple other vehicles.
With the size and weight of these tires, and what I plan on doing to the engine, it's cheaper to use a Rockwell than to beef up a D60/D70/10.25 enough to where I won't be snapping shafts.
A 60 should be ok in the front though, and I really don't want to fabricate all the stuff for the steering and suspension to run a Rock in front. I'd love to run a Sixty9 up front but those aren't out yet and I'd still have to fabricate everything. I thought about running Mogs under it too, but they don't hold up well above 60mph.
