with Panaracer Paselas I did 5 big tours, 38mm, in Spain, Romania and Georgia, we tour off road most of the time, these three countries have off roads for years, any problems with the tires. yes, flats, but I can live with them
in fact remembering well I had no flats with them in 2015 and 16.
Hey, I've got Paselas on two of my bikes plus my fiancee's road touring bike, with the overwhelming bulk of my riding miles on them over the past two years. I love them for a lot of things, including a clean road tour in an area where I wasn't too concerned about parts availability, they just aren't what I think of when I think "tough".
