I was running some smooth tread tires for a couple months till I finally decided I needed some grip! These performed exceptionally well on some sandy trails and leaves me more confident when there's dirt on the pavement. The only bad thing I can say is that its durability isn't that great. I was surprised to find a tire flat after going to the local cafe. I'm currently running them with tubes, so if you know how hard tubeless tires are to seat back on, you know that the patching job took a bit longer than usual. Other than that, I would definitely get these tires again, but I would convert to tubeless by then. Be warned fellow tube riders!
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.
Bought this tire specifically as a front. Between the width (48) and the braking effectiveness, it's a solid choice
