A high performance all-road tire that performs well through a wide range of inflation levels. The mix of small, closely spaced center knobs and longer, taller cornering tread blocks is appreciated in soft or loose surfaces. ZSG (Zero Slip Grip) natural rubber compound provides consistent performance through a wide range of temperatures and wears well. Bead-to-bead puncture protection belt. 126tpi Advanced Extra Alpha casing performs well through a wide psi range, minimizes rolling resistance. Actual width of installed tire can vary by 6mm or more depending on inner rim width and inflation pressure. See technical info for more details. Tubeless compatible up to 60 psi.

Best tires I've had so far, along with the Schwalbe Marahon Supreme. On the road I can keep up with roadies with bit of effort on my 650bx48 mm Gravelkings, on the dirt roads they're only sketchky in 2" sand. Also good grip while cornering, but be careful when breaking hard on asphalt because if you lock the wheel they'll soon lose grip and make a screeching sound which draws your attention to release the brake.

These are great tires. Thanks to the guys at REI for directing me toward the tires.

Super happy with my Gravelking SK's, own two sets, 38's and 43's, have ridden these since April 2021 (2/2023 current) Have not had a single flat with either set. 43's are Big Bird Yellow Tubed and the 38's are purple fuscia tubeless. Raced them, Bike packed with them, single track, double track, rocky terrain (aka baby heads) gravel rough, smooth and some railroad ballast. Being in Oregon they have seen wet days to, thus mud. Bought another set in Jan for 2023 season. Depending on the rider, their skills, will result in varied opinions... For me, these are spot on, from slow rides to nuking corners, I'm happy

I'm very pleased with these tires. They are lightweight and I can take them off with one iron and remount them with no iron at all (just fingers!). I had been running 700x 32 slicks and the subtle tread gives me much more control in sand and gravel but still rolls very nicely on pavement.
Fast on pavement, high-ish volume, side knobs lack bite in loose conditions.
Purchased a set of 48mm for a gravel bike build. Went out for first ride and lost the rear tire by mile 12, riding on mostly clean pavement. Sealant was unable to seal it. Got it home and tried plugging the hole - still won't seal.Never had an issue with punctures on my road bike. Will be looking into other options for gravel.
Punctured multiple times with just light gravel and trail riding
The Panaracer SK tires are the most unreliable tires that I have used on my various bikes. I can’t even get them through one season of riding, for both gravel and pavement, without the tread completely wearing down to nothing. They have a nice, smooth ride, but I can’t recommend them.
I got just about 1000 miles on my pair of 700x38s tubeless before finding a dreaded goats head thorn with the rear tire, directly mid-tread. Wouldn’t seal with the Stans sealant and I didn’t have a plug. Ended up running tubes and they’re now backups. They rolled pretty well and handled chunky gravel and single track. Tread held up well also.
Robust tire, good flat protection. Mediocre grip in loose conditions. Ride is wooden. Long tread life
