The Panaracer GravelKing SK 650B Tire is ready to take on even the most hardcore roads. Featuring a more aggressive tread than the standard GravelKing tire, the SK utilizes Panaracer's ZSG Natural rubber compound for optimal natural puncture protection and grip.

Go beyond the end of the road with confidence thanks to the 48mm-wide tread with raised knobs through the central patch, while more sizable blocky shoulder knobs keep you rubber-side down while cornering. The AX-α low rolling-resistance casing and anti-flat puncture protection breaker keeps the tires rolling even when the terrain gets rough.

Take the comfort and durable protection to the next level with a tubeless setup, supporting inflation pressures of up to 60 PSI.

Available in Black or Brown sidewall.

Available in 700c sizes as well.

Using these for road grade to semi-loose gravel. Supple feel. Good cornering. Great price.

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
