Touring off road does not require a bombproof tire, it does not exist anyway. It requires good riding technique and experience changing and repairing tubes. You want a tire that fits your rim properly and can be removed/replaced under weirdly adverse conditions. You should practice in rain and cold so you know how the rubber and your fingers work. You may decide you want to carry spare tires into the backcountry, or wherever you decide to explore, in which case you need only consider folders.
