- Panaracer GravelKing TLC 40
(100% is best)
The Panaracer GravelKing is one of the most requested tires in the CX/Gravel section. The bigger sizes of the GravelKing (32 and up) come with a TLC (tubeless-compatible) casing that should make it easy to set these up tubeless. You can choose between brown sidewalls for a classic look or black sidewalls for a more modern look.

Just like pretty much all Panaracer gravel tires, the GravelKing uses the "ZSG Natural Compound" that, according to Panaracer, offers a low rolling resistance and high durability. The casing is an "Anti-Flat Casing" with an extra layer of puncture protective fabric that runs from bead to bead.
In the 622 (28") size, the GravelKing TLC is available in 32, 36, and 40 mm wide versions. Wider versions (38, 42, 48 mm) are available in the 584 (27.5") size.

| 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 TLC 40
(100% is fastest - lightest - highest - strongest)
The Panaracer GravelKing is a very fast gravel bike tire but be aware that it doesn't have any knobs to provide off-road grip. Puncture resistance and thickness of the tread is below average while the sidewalls offer average protection at best when compared to other tires in the CX/Gravel section. To us, the GravelKing looks a lot like a very big road bike tire.
If you don't need the knob height or puncture protection and your riding conditions suit the GravelKing, the GravelKing is one of the fastest and lightest choices out there. You can compare the GravelKing to other tires on the CX/Gravel overview page.
