FWIW .. I have used the Continental Travel Contact tires that came on my Trekking Bike.. Rails to trails being well graded and not much climbing at all ..
they would be over the actual needs as they had long tours on the road, and continuing on past the end of the pavement , in mind..
I used mine for a few years, buying the bike they were on , 4 years old.
A smooth band center, so rolls easily on the macadam , with a row of knobs on the edges for the unpaved roads..
gatorskin mesh reinforcement the whole casing width, for self supported touring loads..
I've had a bent rusty nail go thru the sidewall not the tread....
Only took them off for Schwalbes, because townsfolk kept assuming the tread design was a knobby tire worn bald.. and repeatedly telling me..
