    The king.

    Continental’s 29in Mountain King II mountain bike tires are equally happy rolling through muck and cruising hardpack. Beefy shoulder lugs improve your cornering abilities, and siped center lugs are placed with the optimal spacing pattern for excellent braking and traction. The tread pattern also resists deflection to keep your speed up on fast trails. ProTection is a layer that encircles the tire to fend off punctures and resist wall-to-wall damage. Continental’s Black Chili rubber compound lengthens tread life and dampens your ride against vibration for smoother days on the trail.

    Great all rounder

    • Familiarity: I've put it through the wringer

    I've ridden several pairs of the Mountain Kings over the past several years (front and rear) and I've been very satisfied. They're not the fastest rollers, but I'm not trying to set any Strava records. They do provide great traction on loose trails and grip the corners with confidence.

    I run 2.4's on Stan's Crest hoops. To mount them tubeless, I found it easiest to put the tires on the rims still dry, then wet the sidewalls with a damp rag, then inflate with my compressor to about 50-60psi to set the bead. Then I deflate the tires and add the Stan's sealant through the valve stem. Works every time and no mess.

    I run them around 20-23 psi. for my weight (180lbs). I've had only one flat in the past several years of riding the Mountain Kings. The sidewalls do wear out after a couple seasons and sealant starts to seep through.

    A Very Underrated Tire

    • Familiarity: I've used it several times

    I've used these tires in the past, when they first came out (apparently 2011). Since then I've tried several brands and tires - I enjoy the mechanical aspect of the mountain bike nearly as much as the actual riding, so I'm always changing things, especially tires.

    Over time I ended up sticking to Maxxis primarily - most recently the Ikon 2.35 front / rear, or DHRII front / SS rear, etc. Bike is the Yeti 4.5. Terrain is technical rocky, big climbs and a high preference to difficult. Believe it or not the Ikon 2.35 is hard to beat for traction and speed. But.

    I recently threw on the Mountain King II 29x2.4 front and back (I would normally run the XKing in back, but wanted to try something different). First ride out was a fairly smooth 2000 foot climb, then a fun, choppy, fast, rocky descent and back into smoother terrain.

    As others have said, I forgot how fast these tires are - this is probably the most surprising aspect. For as aggressive and "blocky" as they are, they feel smooth and quick on the trail.

    Cornering felt excellent, but I'm still a little hesitant to push it until I reacquaint myself with this tire. The rear wheel seems to lock up very easily (skid) with this as a rear tire, but I may have to adjust my technique.

    I'm 175lbs and running 17psi front / 20 rear - the sidewalls are so rigid, you can easily get away with lower-than-normal pressures. From my past experience, the ProTection sidewalls are very reliable as well.

    All in all, again I feel there isn't much talk about this tire, but should be (even though it is on the way out with a 2018 replacement as I understand).

    Regarding width: I’m getting just over 2.3” at 17/20 psi and the full 2.4” with 50psi (done to stretch tires initially).

    Tires are very subjective in my opinion, but I'm definitely happy with them and will leave them on for a while.

    Size matters

      I purchased 29x2.2, I received and installed a tire that is measuring 2.0. To verify I was measuring correctly I measured the other two mtn. bikes in our house, all equipped with Continental 2.2 tires and they measure correctly. What happened? Mislabeled? Factory seconds?

      Going Tubeless ? - Pack A Lunch

        Tires look good and fit well. I tried mounting them tubeless and proceeded to get my caboose handed to me for about an hour and a half. The sidewall is fairly stiff and makes it slightly difficult to seat the bead. After swimming in Stans for a while i managed to get it to seat. I will update on the usefulness of the actual tire when I get out next.

        Mountain King, Protection, Black Chili

        • Familiarity: I've put it through the wringer

        I am riding a Yeti SB4.5 with a 2.4 MK in front and a 2.2 in back. Mounted on Stan's Crest rims. I have about 600 miles on the set, exclusively off road. Most of my riding is done in the Grand Junction, Fruita, and Moab areas. Probably about 50% at the modestly technical Lunch Loop trails. Lots of rocks, moderate drops etc. No flats to date, although it appears that some bead damage has occurred because there is some leakage of sealant around the edge of the rim, but they still hold air well. The tread is in great shape, however. The leakage could also be due to dirt but I'm too lazy to take them off and clean the rim.

        I agree with another rider that there can be a WTF moment or two if you don't corner aggressively enough. I find myself holding my breath a bit waiting for the side knobs on the front tire to hook up. They do eventually, you just have to commit.

        They are remarkably fast rolling for a tire of this type. I found them easy to mount and that it takes a few days for Stan's sealant to seal the sidewalls completely.

        Oh yeah, my riding weight is 150 lbs, which is how I get away with Crest Rims around here.

        Rear Tire Bliss

          I love these things. I've been running them on my 27.5 5010 for a full season and am about 150 miles into my the 29" version on my Hightower LT. I have had 0 issues with durability or grip, but they definitely required a compressor to get them seated. I've been running them around 25 PSI all over Utah/Idaho/Montana and look forward to many more miles. Trail King out back, so Conti's all around for me. I feel the rolling of this tire and the grip of the trail king make for the perfect tire setup.

          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

          • Familiarity: I've put it through the wringer

          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

            • Familiarity: I've put it through the wringer

            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.
