What rims are on the bike? If you had the time, it would be interesting to measure the inside width of you rims. How about doing that when you change your tirees, and let us know the size. That could settle some of the questions raised in the discussion. It might be good to do before you order the tires.
I've done a lot of touring on 25 mm tires, and they are not bad. I have also done a lot of touring on 28 mm tires, including a trip across the U.S., but the rim was probably a little wider than your rim.
