Panaracer GravelKing Slick TLC Folding Tyre

Product Information

Front doesn’t show much wear, but the rear has lost all the bumps in the center. I’m guessing it probably has quite a few more miles left in it, but I haven’t found any reference for wear markers. Price The eyewatering prices of these "gravel" specific tyres set me off in search of less fashionable but cheaper alternatives. And not tubeless either, I remain unconvinced of the benefits relative to cost of converting. I just don't suffer enough real world punctures to give it cause for serious consideration.

NOTE: As of 2021, we've improved the puncture resistance tests and now provide 'Total Puncture Score' as the main puncture resistance indicator. tofudog415 wrote: I use the 38 mm (622-40) Terreno Zero as my rear tire. When new, it inflated to about 39 mm on a 21mm ID rim. After six months, it has stretched out a bit to about 40.5mm. I typically have 38-40 psi in it. I have punctured it once since I installed it, but it was one of those stealth punctures that sealed without my knowledge. Only discovered it when I was pumping up the tire and noticed an abnormally low starting pressure.They have indeed been a little more comfortable of a ride. Much of that may be from only inflating these to 90 psi rear and 85 psi front. The GP4000 I was doing 110 psi rear and 100 psi front. So, I don’t know how they would compare at the same inflation. They have real good grip and I have always felt confident riding on them. I have also had no flats, which is great. I do think I lost a little bit of speed with these. This is probably due to them being a little higher rolling resistance tire plus the lower inflation. Max inflation for these is only 105 so I wouldn’t be able to go as high as I did with the GP4000. The Gravelkings are also quite a bit heavier as they are supposed to be about 320 grams vs 220 grams for the GP4000. Durability At 309g per tyre it's pretty light, and only 19g heavier than the 32mm version. Meanwhile the 38s give a slightly bigger jump at 337g, so you could argue these are the sweet spot for weight versus width. Certainly they're a lot lighter than the outgoing 40mm Schwalbe G-One All Round tyres that came with my all-roads/gravel bike, which are about 480g. Our own very low rolling resistance as the premium compound. Its enhanced wear resistance makes it perfect for a long lasting training tyre with an excellent ride.

On soft surfaces (loose sand, grass, etc), almost all grip will be created by the knobs digging into the surface, and our test results will be of little use. Given these shortcomings, we feel our grip test, combined with the knob height measurements, will still be valuable information when comparing tires.This compound has the same low rolling resistance as the Ultima compound. Its enhanced wear resistance makes it perfect for a long-lasting training tyre with an excellent ride. ZSG Natural Compound: This compound has the same low rolling resistance as the premium compound. Its enhanced wear resistance makes it perfect for a long lasting training tire with an excellent ride. On the road they felt amazing, the comfort of a large volume tyre on a carbon gravel bike is really welcome. On mixed surfaces they didn't inspire much confidence.
