Looking for a tire that’s more aggressive than the mixte-tread GravelKing? The GravelKing SK might just be the tire you need for the more hardcore roads. Aggressive knobs, ZSG Natural rubber compound, puncture protection breaker and AX-α special low rolling resistance casing make the Gravelking a go-anywhere tire. And tubeless compatible up to 60 PSI! The Gravel King SK + model has side reinforcement with Protite and bead-to-bead nylon puncture belt, resulting in a 4ply, super tough casing.1
Japanese tyre company Panaracer Gravel King SK + has been quick to offer a range of gravel-specific tyres, becoming a significant player in the burgeoning market. Measuring 43mm wide, these GravelKing SK tyres are tubeless compatible and feature a tread pattern that excels both on and off road, with a tough carcass that can withstand some abuse.
The GravelKing comes in a variety of widths and tread patterns, but this SK (Small Knob) is probably the pick of the range for the latest generation of adventure bikes like the Kinesis Tripster AT, Mason Bokeh or Open UP. As well as the 43mm tested here (which was called 40 but actually measures 43, and is now labelled as such), the same tread pattern is offered on 26, 32 and 35mm width options if your frame doesn’t offer enough clearance.
- The sample 700c x 35mm Gravelking SK tyres weighed 382 and 384 respectively, just a tad over their advertised weight.
- The sample 700c x 40mm Gravelking SK tyres weighed 496 and 504 grams respectively, again a small amount over their advertised weights.
Mounting the Panaracer Gravelking SK
The 700c x 35mm and 700c x 40mm versions of the Gravelking SK are very easy to mount. The best way to demonstrate the ease at which this process happened is to link to the video review (below) of the Topeak Joe Blow Booster Pump I reviewed earlier. The video below will jump directly to the spot where I inflate the Gravelking.2
SIZE & COLOR
The Gravel King is available in two distinct flavors:
- Gravel King – The regular file-tread version, available in 700c x 23mm to 700c x 32mm – mostly suited to pavement and some of the nicer gravel roads around the world.
- Gravel King SK – Featuring a more aggressive tread and wider casing for the demands of true gravel cycling. This model also happens to be tubeless ready and is available in 700c x 32mm, 700c x 35mm and 700c x 40mm widths. Featuring Panaracer’s ZSG Natural rubber compound, puncture protection breaker and AX-⍺ special low rolling resistance casing make the “Gravelking a go-anywhere tire.”3

WHERE TO BUY
My Overall Impressions About the Gravelking SK Tires
Should you invest in a pair of Gravelking SKs? Choosing any tire is a deeply personal decision and includes factors like where you ride, the surface conditions you favor, preferences, and so forth.
But, after riding with three sets of these tires across more than 8,000 miles, they’ve performed almost flawlessly and are reasonably priced compared to the competition. As a result, I can’t recommend them highly enough. I’m always excited to ride them and see how they’ll perform in different scenarios and conditions.
But, if you ride in wet conditions with lots of mud, their tight central tread pattern might not deliver optimum performance.6
Our results show that the GravelKing SK is made from the same materials as the regular GravelKing. As expected, the rolling resistance is higher because the SK has a more aggressive tread pattern than the regular GravelKing that is nearly a slick tire. All other test results are almost the same.
We think that the GravelKing SK is a great tire for gravel use, although we think that the puncture resistance is not great, which is why this tire scores slightly lower. Visit the CX/Gravel overview page to see for yourself how this tire performs when compared to other cx/gravel bike tires.7
