The Panaracer GravelKing SS (Semi-Slick) TLC is a gravel bike tire positioned right in between the nearly-slick GravelKing and the GravelKing SK that's made for rougher conditions. The GravelKing SS features a tread pattern that we see more often on gravel bike tires: a nearly-slick center tread and bigger knobs (GravelKing SK-like) toward the edge of the tire.

From a construction standpoint, the TLC (Tubeless-Compatible) versions of the GravelKing (read our review), GravelKing SK (read our review), and GravelKing SS are identical as they all use the same casing and compound. The TLC casing is made from Panaracer's "AX-Alpha Cord" that, together with an extra layer of puncture-resistant material that runs from bead to bead, makes this an "Anti-Flat Casing". The compound is Panaracer's ZSG (Zero Slip Grip) compound that's used on many other Panaracer tires.


Just like many other Panaracer tires, the GravelKing SS is available in a large range of sizes that range from 32-622 up to the 43-622 and 48-584 sizes. We've tested the TLC version as it appears to be the most popular because of its versatility. The TLC version gives you the choice to use it with an inner tube or in a tubeless set up with sealant.

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.

The Panaracer GravelKing SS performs excellent in our tests. In the rolling resistance tests, it shows good performance and comes in right between the very fast GravelKing and still quite fast GravelKing SK. The real strength of the GravelKing SS can be found in the puncture resistance tests of the tread as it scores much better here mainly because of the increased thickness of the tread.


If you've suffered cuts, punctures, or lack of durability with the regular GravelKing, we highly recommend you to try the GravelKing SS as it's a more solid gravel bike tire that also should last a bit longer. The increased strength and durability comes at the cost of a few watts of rolling resistance and an extra ~70 grams per tire increase in rotational weight.
