Depends on your use. 265/70s are wider, more floatation. 245/75s are narrower and will be less affected by water, slush, loose surfaces at speed. Me I prefer the narrower because hitting a puddle at highway speeds has less effect on the straight line tracking. But I drive more highway than anything else. I'd run 255/85R16s. A 33x10x16.
Yer question asks more questions. How/where do you drive?
My Uncles first Jeep was a Government Issued Jeep in 1944.
Back when ALL Jeeps were Government Issued.
