The Plus version of the Panaracer Gravelking SS (Semi-Slick) TLC is a reinforced version of the non-Plus GravelKing SS (read our review) that we tested a couple of months ago. The non-Plus GravelKing SS turned out to be quite a strong performer in our tests as it already offers much better puncture resistance when compared to the "regular" GravelKing while being just a bit slower.

The Gravelking SS Plus comes with an extra layer of "ProTire Shield Plus" anti-puncture material that protects the tire's tread and sidewalls. The bead-to-bead protection is different from the "regular" Gravelking Plus (read our review) that we tested a while back as that one comes with an anti-puncture strip that only covers the tread. Our initial thought was that all the Panaracer "Plus" versions would offer the same protection, so we're a bit surprised by these differences.


Another indication the "Plus" versions do not always offer the same protection can be found in the specified weights of the Gravelkings. The "regular" Gravelking is just 10 grams heavier than the non-plus version in the same size, while the GravelKing SS Plus comes in 50 grams heavier than the non-plus version. As there are many more versions of the Gravelking available, and it's a good idea to check the specified weights to get an idea about the added protection of the Plus version.

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 Plus TLC offers massive protection with very high scores in both the center and sidewall puncture tests. Given the high level of protection, rolling resistance is still reasonable, but we wouldn't advise this tire if you're looking for a fast-rolling gravel bike tire.


The main thing that we've learned from this test is that not all Plus versions of the Panaracer Gravelking come with the same level of protection. The Plus version of the regular Gravelking only offers a protected tread, while the Plus version of the GravelKing SS adds full tire protection, including the sidewalls. If you want to know the protection levels of the other versions of the Gravelking, look at the specified weights -> If it's just 10-20 grams higher, it's protection under the tread; if it's 40-60 grams higher, it's bead to bead protection.
