The Panaracer GravelKing SK is a version of the GravelKing (read our review) intended for somewhat heavier gravel riding. The construction with the "Anti-Flat" casing and "ZSG Natural" compound is the same as the regular GravelKing we tested before, but with a more aggressive tread.

The larger versions from 32 mm and up are only available with the TLC (tubeless-compatible) casing that makes it easy to set these tires up tubeless. The GravelKing SK is also available in slightly larger sizes up to 50-522, 54-584, and 54-559. All sizes are also available with both black sidewalls, or brown sidewalls for the more classic look.

Rolling Resistance
Real tire width in mm:
30-32 = 33 psi/2.3 bar
33-35 = 30 psi/2.1 bar
36-40 = 27 psi/1.9bar
Extra Low Air Pressure
28.3 Watts
CRR: 0.00848
The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width.

All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs.

Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.

Conclusion


  • Panaracer GravelKing SK TLC
Performance compared to all other CX/Gravel tires
(100% is fastest - lightest - highest - strongest)

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.
