Basically I'd like my truck to ride on some 44's (more likely 39.5 boggers or 42" TSL's), but I'm concerned with the dirt road drivability. I do some high speed desert blasting from time to time, and I don't know how a huge bias tire like that is going to react. Anyone have any experience with large tires at speed? Or should I stick to a radial (i.e. 37-38" SSR or TSL radials) if I plan to go in the desert? Ride height into consideration, it will be the same 6ish inch lift height in any case. I just want to know how those big tires will act.
