Panaracer Gravel King SKs have become my go to tire for gravel. Very durable so far (no flats yet). I have these on a pair of 650b rims and also 700c set on a pair of Easton rims. The 650b's are more difficult to get on and off for sure. Even broke a Pedro's lever putting one on which has never happened before. Would hate to try and fix a flat with these on a cold winter day, but that just hasn't been an issue. I love the tread pattern of small block knobs. Rolls well on pavement too and is not noisy at all, unlike some other gravel tires. I have heard that Panaracer makes tires for Compass which is sort of a cult brand among the gravel glitterati.
