I ride a Cannondale Slate with 650b x 42 tires. I’ve been on Parimotos (great ride too puncture prone), Gravel King Slicks (much like the Parimotos), Specialized Sawtooh (flat free but harsh ride and heavy), some Kenda e-bike tires (similar to Sawtooth). I’ve only gone out one time but these are fantastic. Plenty of grip and they roll great. Highly recommended.
