I've tried a few different gravel tires and settled on these. The 40c gives a good ride wgood traction and durability and feels like it rolls faster than others. Im a larger rider and this tire gives a nice ride for me w47-50 psi.
Have about 100 miles on it now for a Tandem bike. Nothing to complain about. Good traction, holding its own despite the heavy loads. Higher PSI def works better for these type of usage.
