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.
Pulled my Dad's old Raleigh out of the garage last month. Tires looked like they had leprosy they were so dry-rotted, bummer. Luckily these replacements were cheap and easy from Western Bikeworks. Now I have a working town bike to go get that growler refilled. The black sidewalls are nice, stay looking clean. Pro tip if you are fixing up an old bike like I was, just go ahead and replace the tubes AND the rubber rim-strips (covers the spoke heads) cuz they are going to be rotten too when you get in there.
