The main issue is to have sufficiently wide tires to prevent pinch flats due to underinflation. You will probably need at least 700x28c tires inflated to at least 110 psi in front and 120 psi in the rear to avoid pinch flats and possible rim damage. Keep in mind that not all tires are rated for those pressures.
