My go to tire in 35mm width for my 75/25 road/gravel riding. Tire has not let me down, is smooth riding, and nearly as fast on the road as my previous road only tires. Recommend.
Review by Ray Marron
Great gravel tires, no more pinch flats or penetration flats. Can run to 20-40 PSI depending upon the terrain. finally a gravel tire with performance
Review by Mark12
These tires roll fast and stable when going from roads and paved trails to limestone trails! As a bonus, they are comfortable on rough roads. I have been running them for two years on my trail bike and i Not changing!
Review by Thomas
My third set of gravel kings. A good solid all around tire. I�ve put thousands of miles on them. They ride well and I haven't had any sidewall cuts or punctures. I run them tubeless and any punctures from debris have sealed quickly, or was able to plug. They seat easily and well on various different hooked and hookless tubeless rims. They also hold sealant well, and don�t require any specific sealant like some other tires. Maybe not as supple or fast as some higher end and more expensive tires, but overall a great tire for road or gravel.
Review by Luke
I purchased these tires to be more road biased but still climb the gravel/fire roads here in the Bay Area. The suppleness of the tire works well with my Topstone's kingpin suspension to add another layer of comfort. The 38mm X 700c tires actually are about 40mm wide on 25mm ID rims (they are marked 40x622). The 120 tpi casing is noticeably supple and was a little bit of a challenge to get on the wheels (HED Eroicas) with a single tire lever (crank brother's awesome one) but that also meant that a regular floor pump was able to set the bead on the rim. After three months, the bead has stretched and removing from the wheel is very easy.
Performance wise, The + casing has allowed me to forge rock strewn stream beds as well as bomb smooth tarmac hills cornering hard. The file tread and supple casing means that lowering the tire pressures allow me to climb gravelly fire roads and trails up to about 14-16 degrees of incline ( any steeper, and I have to get out of the saddle and then the tire slips and its game over). On the road, I can keep up with most group riders but I'm sure that the width and my gearing (46/30 & 11-34) start to be a factor. The extra wide tread does feel more confident at high speed cornering.
Wear is okay- at 1500 miles, the rears have worn the file tread off the center 10 mm wide section and has flattened. The fronts are barely showing wear. however, I did get a 2 mm cut on the rear tire near where the tread is worn. I was fortunate and didn't even know until this morning when I discovered that I had almost no air in the tire. It would hold air at 25 psi- unloaded. I believe that the wear is about where the protection starts to become an issue. I've already ordered another rear and am pretty sure I'll get near 3-4000 miles off the fronts.
If this was my only wheelset, I might consider the Gravelking SS next time. However, if you have another set for off road duties like me, I feel that the Gravelking slicks are a good all around tire. I am considering 35mm when the fronts wear, but am not willing to trade the offroad capabilities that 40mm allows because some of the fire road climbs do take 10-20 miles of road riding to get to. Having a very competent road tire that can cover some offroad in a pinch is the best compromise for me and allows me to run a more aggressive gravel tire on my other wheelset for the closer rowdy rides in my local regional park.
Review by ggswanson
I bought these tires for smoother less aggressive gravel rides and the occasional bike commuting when I want to hop off the bike and not be wearing road cleats. At the 38mm width they feel slow on the road but are certainly comfortable. If you want to make pace on pavement, maybe go with 28 or 32's. But on a recent gravel ride that included soft muddy "roads" with tire ruts and standing water they worked amazingly well. Hardly any squirm and no slip to speak of even when climbing. I was using tubes so you'd probably get even better traction tubeless and a little less air pressure. But in situations where I thought I was going to be in trouble it was smooth sailing. If I knew the conditions ahead of time I would have used the GravelKing SK, but this tire will handle far worse conditions than you would think.

I have these tires on my gravel bike with fenders for 90% pavement. They grip and smooth out the rough tarmac. They do not feel like a 32c, I don't feel impaired climbing with them. I run them tubeless and around 38psi and have about 200 mi on them so far.
Review by Josh
Bought these to replace a set of knobbly tires that ended up being too wide for my frame by a nano meter.
I went out on a trip with every kind of gravel you'd expect to find, smooth rolling hard-pack, squishy mud, freshly laid gravel, chunky deep stuff, baby-heads, and pavement. These worked best on the pavement up through loose gravel, but as soon as things got wet, or when the grade went to the double digits, things got sketchy.
I probably ran the psi too high for some of the stuff I encountered, but I didn't have these set up tubeless. The tire and my rim don't much like each other, and I couldn't get a tight seal to set the beads. That's the only reason I set this to 4 stars. If they could be tubeless for me, probably would be the best summer tires around.

I'm using the GravelKing+ 35mm as my mostly urban tires. Riding pavement and some packed gravel. These are a super smooth riding and very grippy turning tire. I really like the way they ride.

These tires rip on everything and we're way grippy, hold up well even in wet and a little mud, granted you gotta be on focused up when things get a little muddy. When standing and it get steep definitely need to keep your weight down and back as they will slip at times.

I put these 35's on my Surly Straggler to replace the stock Knards it came with. I do most of my riding on city pavement and didn't want a full on gravel setup. These ride great on pavement and absorb the bumps nicely. I also hit some dirt and gravel occasionally with no issues. They're beautiful too, I just left the bike in my living room to stare at it once these were on. Coming from a 23 road bike setup for years putting these on was life changing. Still feels like a road bike, but with added comfort and confidence.
Review by Cliff
Very good grip on gravel, and very good on road. Looking forward to miles on miles of riding on these tires.
Review by helodrvr
My use is primarily country secondary roads mixed with a little bit of gravel exploration. I use the 700c x 38mm with tubes on a Rivendell A. Homer Hilsen (57c). I find the tires to be very responsive and relatively light for the size. Running them at 50-55 psi with the tubes has worked very well for me (215 lbs.) I have ridden these tires over the fall and have had no issues at all with punctures or flats. I am very pleased with them.
Review by CM
Over 500 miles so far on everything from pavement to rocky singletrack, I don't pull my punches and these tires haven't flinched. I've been using the standard GK 32's for road riding for years and thousands of miles, and no issues and no complaints. The GK+ were relatively painless to install, and they've performed flawlessly so far. They're fast and they're bulletproof. Maybe not the most supple tires in the world, but smooth enough to keep my longer mixed surface rides fairly comfortable. Highly recommended.
Review by BeltedOneSpeed
Previously ran GravelKings (no "+") on both my and my wife's single speeds. She's at 700x38 and I'm at 700x35. Haven't found a tire that I like more yet for this application, so the addition of puncture-avoidance is a bonus. No difference in ride quality and tread pattern is the same, so this will be my future go-to for replacements. About 4 years ago, we started doing mostly urban rides around Atlanta that occasionally include dirt paths between neighborhoods and long gravel stretches while our 700x25c road bikes collect dust.
Review by PDXcycling
Getting these tires seated (tubeless) on 21.5mm internal rims was unlike anything I'd experienced to date and, while I eventually figured it out - tube in for 24 hrs (any less = failed attempt), remove tube/leave one bead seated, add sealant, use a booster pump - the amount of experimentation (aka failed attempts) required to even seat these things was nuts. Flash forward 1 month and after 6 rides with these tires on my gravel bike, I ripped them off. Sure the ride is nice, they corner well on pavement at high speeds, and provide acceptable control on light gravel/dirt roads, but 3 punctures over the course of those 6 rides is simply unacceptable.

Mostly roads, with 30-40% easy gravel riding and these are perfect for that in the 32's.
Review by Jason
Purchased these for a gravel race with a lot of pavement and have really grown to love them. Usually run them tubeless at 38 psi and up to 50 on a recent all pavement ride. They do get a little squirrely on loose gravel and I wouldnt run them in mud. Initial tubeless setup had a lot of sealant leakage throughout the porous rubber. After about 5 rides seemed to diminish. Greatly reduced rolling resistance over the SK, which I really like for more technical conditions.

Fast and smooth, time will tell about puncture resistance. They rate well.....
