Depends on how rough those roads are. More and larger rocks, ruts, mud pits and holes in the road will demand wider knobbier tires. Think of the pounding your arse, back and arms are going to take while you're out there for hours on end. Will you need 2" tires to smooth out the road? Depends what roads you plan on riding.
