I'm running 33's, but soon will be installing 1 ton axles with 4:56 gears. This vehicle will not need to spend time on the highway. I play most often in mud and deep snow. Can't decide between boggers in 38.5x11(too skinny) or 37x13(too short) or be forced to run on 16.5 rims and go to a 39.5x18 (too wide for snow) or 38x13 tsl's (not boggers) Please help as I'm spending way too much time thinking about this. I've only got 340HP to spin these so 40's are out of the question.
