Interesting feedback everyone. That makes sense. Those sidewalls are designed to be supple, not strong. Not sure what they use for protection along the tread. They seem to be on par with a race tire, not a gravel tire.
Most of the dirt roads around here don’t have much chunky gravel on them, but when they do get graded, the fresh chunky gravel can be pretty hard on sidewalls.
I don’t recall them really having tubeless tires until the last year or so – although that may just be a change to the tire bead rather than the tire themselves.
