there are many glasses too hard to see on the road, flats come when they come, one does not have any influence ...
of course, with Schwalbe tires one is on the sure side, but rolling feeling is poor.
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.
