Get a grip.
From mud-slickened trails to stump-riddled runs, Continental's 29in Mountain King II UST tire with ProTection motors through muck, yet rolls fast on hardpack. Beefed-up shoulder lugs improve cornering while well-spaced, and siped, center lugs ensure braking and traction grip.
The center lugs are also placed in a tilted, diamond shape that resist deflection — to improve speed retention on fast terrain. For durability, Continental added an additional layer that encircles the tire to guard against punctures, what it calls ProTection. This protection reaches wall-to-wall to resist damage all the way around, and it does not harden or reduce the dampening characteristics of the Mountain King II's proprietary Black Chili rubber compound.
This compound is a refined synthetic rubber with nano-particles to create a formula that reacts to surface objects more quickly, improving grip. These particles also form a tighter bond to improve compound strength, lengthening tread life and reducing the chances that lugs will rip and tear.
The Continental Mountain King II 29in ProTection is UST and comes in two widths: 2.2 and 2.4in.
- Black Chili rubber compound
- Beefy tread pattern
- ProTection layer
- Available in 2.2 and 2.4in widths

Are these tires tubeless ready?
2.4 EZ Tubeless Set Up / Not Super Wide
- Familiarity: I've used it once or twice and have initial impressions
Measures 2.25" wide with 25PSI on my 20mm wide DT-Swiss X1700 rim. Holds a lot or air volume though. Very easy set-up for tubeless. I used a compressor but could have used a pump. One ride in the dry desert southwest up front >> all good.
Love my contis

So I became a conti lover with their 4000 series road bike tires. When it was time to re-up with a new meat on my mtn bike I decided to stick with the brand. They never wash out, sticky as can be. I've never had more confidence in the corners. Happy with my purchase.
Traction + Fast Rolling
- Familiarity: I've used it several times
Great cornering traction and still fast rolling. I was not very impressed with the side wide, seem very thin and not very durable. Easy to set up tubeless
Great off season XC tire
I'm running two of these right now on my race bike. I'll admit, I was skeptical at first. I figured they wouldn't roll as quickly as a X-King. I was right, but it wasn't as drastic as I though. The Mountain King still rolls quickly, and it descends wonderfully. I would recommend this as an off-season tire. Probably not quick enough for races, but great everywhere else. Due rivulets is solid as well.
Durable, high performing but quirky

I switched to these when I moved from the west coast (dry, loose) to the east coast (wetter) and wanted a good all-around tire that would roll well, still shed mud, and grip well. I also was hoping it would last a long time. I definitely got all that.
I have 1500 miles on a set of the 2.2 in protection and you have to look really closely to see any wear. The tread has barely worn down. I run them tubeless with Stan's and I've had one flat in that entire time which easily sealed itself. I'm amazed by how durable they are, especially given the weight (the 2.2s weigh ~730g, close enough to listed). No, they're not the lightest, but a flat will cost me more time in a race than weight. They are on the smallish side for a 2.2, but not terribly so. I also have a 2.4 and that's about the size of a 2.4 Trail King.
Oh yeah, I race on these. I use them for training and racing, and I'm happy with how they perform; they grip really well (with one caveat) but still roll fast. I hate Race Kings because they have no traction; these have much, much better traction but not a huge rolling resistance penalty. If you're really concerned about weight and rolling resistance and don't have slick conditions at all, go for the RKs, otherwise these allow cornering without wizardry.
Now the caveat: they corner well, once you get onto the side knobs. The weird thing is there's a "dead spot" between the center tread and the side knobs, meaning if you lean them slightly you'll wash out as there's no tread there, but if you lean them hard the side knobs hook up really well and they grip and corner great. Basically, you have to adjust your cornering style to lean hard through turns, maybe harder than you were before. That took a few weeks to adjust to, though once I did I stopped noticing the dead spot, I just throw into a hard lean and go right through it.
Overall I love them and have two sets. I run 2.2 front and back on full sus, 2.4 front/2.2 back on (sometimes rigid) singlespeed.
Great addition to my growing tire quiver
I got the 29" version of this tire in 2.4 for the front wheel of my Santa Cruz Tallboy. It has excellent grip in loose/dusty/dry terrain and is very durable just like all of the other Continental tires I have tried. This or the Trail King are my go to tires for mountain biking in Utah.
