I'd go to a 305-75 if they fit! You definitely have the torque and the gearing.
It would bring down your rpm about 11%, which would offset the very slight increase in rolling resistance. Probably a net gain in mileage even going up to the big tires I suggested.
Also a smoother rough road ride, as the tires will tend to absorb the smaller bumps better.
