Balances off-road traction with rolling efficiency.

Designed with a grippy tread and reinforced with Anti-Flat Casing, the Panaracer GravelKing SK Tubeless Tire is your partner-in-crime for adventures down bumpy gravel roads where flats and punctures are common. This tubeless-ready tire in wider casing runs lower in pressure for greater bump compliance and excellent grip across rough gravel and bumpy roads. The ZSG Natural Compound balances low rolling resistance with tread longevity, giving you the best in efficiency and durability along mixed gravel and asphalt surfaces. Please note, this isn't the best tire for muddy conditions, as Panaracer developed a specific version of this tire for sloppy muck.

  • Reinforced for gravel grinding along rough stretches
  • Grippy tread for unrelenting grip across gravel roads
  • Tubeless-ready and wider casings for running lower pressure
  • ZSG Natural Compound balances rolling speed with durability
  • Anti-Flat Casing prevents flats and nasty punctures

A great gravel tire

  • Familiarity: I've used it several times

I love these tires. great grip on loose gravel but also smooth on the roads. I have the wider tire and they are a very comfortable ride (35PSI). They seem to be very durable so far. I would take these tires anywhere.

A great gravel tire

Solid through the DK100

  • Familiarity: I've used it once or twice and have initial impressions

Just back from DK100 2018 riding the 38s on Stan's wheels tubeless at about 30lbs and these rode perfectly with no flats. A friend with well know tube gravel tire flatted twice in first 10 miles ! I had solid grip in all conditions including tricky climbs where others spun out. We had a significant mud section where only those with huge clearance could ride as the mud stuck to everything, these tires included. But the mud "self cleaned" on gravel downhill. The tread seemed fine on everything. Cleaned them up once home and they look brand new.

I also was at DK2018. Rode the GK 43 mm on my Moots Routt 45. No flat and no issues with the tires. Held pressure well. Used Stans race sealant on Zipp 30 course wheels. No issues in climbs or descents. I saw plenty of racers with flats on the course.

Glad to hear about the performance of these! Thank you for the feedback!

Tires were nice when they held air. Fairly grippy and rolled quick. On the second ride out, sliced the rear tire and had to boot with a gel wrapper and use an inner tube.


Great tire for gravel, hardpack and road

  • Familiarity: I've used it several times

This is a great do-all tire that doesn't stray too far from the middle. When aired down to 30-40 psi the tires are awesome on hardpack/gravel. Put in 70 psi and they are a solid tire to cruise on the road. Say away from mud and this tire excels in its versatility.
Beware tire volume between brands. I swapped out a 28c Continental Grand Prix for the 32c Gravel King and the volume (circumference of the tire) was almost identical when comparing the two.
Tip for mounting: make sure the bead of the tire is in center groove of the rim, this will allow a little extra give to pull the last bit of the bead over the lip without the need of a tire lever, but it's gonna be tough on the fingers.


  • Familiarity: I've put it through the wringer

I ride my santa cruz stigmata as an all road bike! CX trails, gravel roads, and the tarmac on the way! these tires have performed on all the above surfaces! no punctures or burbs yet after a year of use!

Hi David- I have a Stiggy too. Which size GK's are you running? I've heard they run a bit big, and want to make sure the 38's will fit in my Stiggy. Thanks!

Nice tires, hard to mount

  • Familiarity: I've used it several times

Everyone kept telling me that tubeless is the way to go and I finally decided to try it out. I'd read good things about the gravel king SK tires and have had great luck with Panaracer road tires so the gravel kings seemed to be the logical choice.
As usual Competitive Cyclist service is great and the tires arrived in a few days. I set out to mount them on my Stans Ironcross wheels. These rims can be difficult to mount some tires, In fact, I had a pair of Challenge Strada Bianche's that neither I or the LBS could mount on these wheels. Judging by the bead on the gravel kings I knew I was in for a wrestling match. I could not get the tire on the Stans rim even with a little soapy water for lubrication and a tire jack. After a bit of thought and being too stubborn to admit defeat, I mounted them with a tube on some Velocity A23 rims and inflated the tires to 70 psi and left them for a couple of days. After this I was able to mount them on the Stans rims, it was not easy and still required a tire jack for the last bit of the second bead. Once on the rim the tires were a breeze to inflate- only needed a track pump to inflate and dry seat on the bead. Add a bit of sealant and you're good to go! They hold air well for days at a time.
Running the tires at 30 psi front and 35-40 psi rear they roll really well and are pretty surefooted in loose gravel. I got the 38s which actually measure 40-41 mm when mounted on the Stans rims. Too soon to know about wear, but the ride is really nice. Overall, I'm quite happy with the purchase. My advice to those that buy is have a tire jack handy or go to your LBS with a sad look on your face and maybe they'll take pity on you and mount them for free or a minimal fee.

Is 32c size tubeless compatible? Panaracer's website does not list 32 in the tubeless section.

Sane question re the 35s? If they're tubeless, this is the first I've heard of it...

Great Gravel Tire

    These tires were built to be a long lasting gravel tire that can do double duty on the pavement and that's exactly what they do. The center tread feels great rolling over gravel as well as chip seal and pavement, with less vibration than even Schwalbe's G-One tire. Where I've really noticed this tire shine is how the block tread on the sides helps hold on in loose corners. Like another reviewer said, they're not great if you're just doing mostly pavement with some mixed gravel, but that's not what these tires were made for. The brown sidewalls are also a nice touch. They give my bike a real classy look.

    Touring Tire.

    • Familiarity: I've used it once or twice and have initial impressions

    I got these for multiple day on and off road touring trips. I've only been able to get out on them for a couple light rides so far, (Will update after first big ride) But the grip is more than impressive, and the squish feels really nice under a well seasoned steel touring pig.

    Light, Long Wearing Goodness

    • Familiarity: I've put it through the wringer

    I have been running these 700x35 tires, tubeless, on my Cielo Base racer, mounted to a set of Roval Control SL wheels with a 22mm inner width. I ran them for a good portion of the season and did Rebecca's private Idaho on them. I have been super impressed with the wear life, and the speedy feel on gravel. They are not ideal for pavement but I found them to be very reliable and efficient for off road segments. I mounted them up with a floor pump and have ridden them in the dry and in some mud, however mud performance was abysmal. They aren't meant for mud anyway, but I thought I would throw that out there. They weigh in at around 384g per tire which is quite respectable in this category. I would buy them again happily, unless I was doing mostly road rides with a little dirt mixed in, I would probably just go with the standard gravel king for that.

    Great Gravel Tire for Dry Conditions

    • Familiarity: I've put it through the wringer

    Really like these. I run these between 35 - 40 PSI and they work great. Not for wet or muddy conditions but they sell a separate model for those conditions. They roll well and have a nice substantial side wall.

    Tough and Fast and Controlled

    • Familiarity: I've put it through the wringer

    I did a 100k gravel race last weekend, Cedar City Fire Road 100k. It was climb climb climb/ smooth smooth/ descend descend descend. These tires performed very well.

    The climb were very steep and the descents very fast and rocky. I ran the 40mm tires and at about 35psi; I weigh 148lbs, I will run them at 30 psi next time. With the wide tire and low pressure, I was able to get out of the saddle and climb and still have traction and had tons of bump dampening and control on the descents.

    I installed these tires before the race, because I was getting too many flats on another tire I ran for DK200. This race was super rough and I had no flats with these tires! I know you will love these tires and the look good. I got 3rd in the race

    Tough and Fast and Controlled

    Congrats and thank you for the review!! Any familiarity with the Teravail Cannonball (either width) and if so do you have any comparison/feedback? Based on a lot of positive feedback about ride quality, traction and puncture protection for the Cannonball and the Panaracer GravelKing SK tires I am looking at both in 38 width. Price on these is cheaper. I may ultimately buy both and run on different bikes but I am still soliciting feedback.

    Hi Angus,

    Honestly, I have never used any Teravail tires. I heard similarly good things, maybe a slight increase in quality over the Panaracers. This is purely opinion and you will be happy with either.

    Gravel Royalty!

    • Familiarity: I've put it through the wringer

    Do not look any further. The Gravelking SK's are the best gravel tires that I have ridden. They are fast on hardpack, pavement and singletrack. The sidewalls are nice and stiff, allowing me to run a bit lower tire pressure than other tires. A big plus is that they seem to be extremely durable. Highly recommended.

    Gravel Royalty!

    Hi Brett. Have you ever tested the Teravail Cannonball tires for gravel/trail riding? I am between these two tires as my top choice but I have yet to find anyone who has tested both tires. I do not know how many other brands/tires you tested before the GravelKing SK and I am asking in case you may have tried the Cannonballs. Nice looking Niner as well!!

    I have Stans 29er wheel with 25mm outer diameter and 21mm inner diameter. Currently using 2.25" Racing Ralphs. Wondering what the smallest version of this tire is that I could install on the rim?

    The skinniest tire they make is 32mm, you shouldn't have any problem putting those on your wheels

    Solid Tire

    • Familiarity: I've used it several times

    Purchased to use on my Torker bike for around town. The panaracer gravel king seemed a little more stout and aggressive tread than many of the other tires. The roads are fairly rough where I ride and this tire, so far, has worked well. I was worried it would look a little to large or aggressive for riding around the city but no worries they look and work well.
