For pavement, would a 26 X 2.0 schwalbe marathon supreme be overkill for pavement? I really, really, really don't like flats. I'd be willing to sacrifice a little power for reliability and comfort.
I'm 210 pounds and will be towing a BOB trailer (which are known to be much more flat resistant than weight-on-bike panniers). Will the upgrade from 1.5 inch 26" tire to a 2.0 make me significantly slower?
I also like the ability to see a dirt path and know that my bike could handle it.
Also... is there anything wrong if I were to keep the front tire 1.5 inch and change the rear to 2.0 becuase my fronts last years while the rear will only be good for a few months of heavy riding.
