okay. before you guys say "just buy the mountain king UST 2.4" let me remind that the mountain king 2.4 proTection comes with black chili compound while the UST does NOT. their only UST tire with black chili is the rubber queen 2.4 (weighs 1050 grams).

so my question is: has anyone tried a mountain king (specifically the 2.4 proTection model) with stan's?? thanks ahead of time.

I just installed these tires (protection version) using Stans on a pair of Cane Creek Zonos last night. What's so special about the black chili?

I'm running the 29 Mtn Kings on Bontrager X lights with the TLR rim strips and Stans and they work fine.

Yep, no problem. The side walls need a bit of work, in that you will need to do a bit of shaking and laying on their side etc etc for a while. I have one that is really good and hardly loses pressure and one that is a pain!!

The Rubber Queen is also fine with stans, I think the standard 2.4 is 800 grams?

I'm running 29er MKs on C29SSMaxs.

There were some interesting "pinhole" leaks at first, but the stan's took care of it. They do still loose a little bit of air sitting around...about 1/2 psi per day.

Other than that, they're working fine; albeit I don't run super low pressures either.

Yea I did notice I had to do quite a bit more shaking that with previous tire conversion. Maybe because it was such a wider tire. So what's so special about black chili?

There were "micro holes" in the sidewall big enough to see a tiny bit of stans ooze out of...it did take a lot of shaking/spinning before it stopped loosing a lot of air.

"So what's so special about black chili?

"Black Chili" is a propietary rubber compound developed and marketed by Continental. It is supposed to give better grip, less rolling resistance, and longer tread life than standard rubber compounds. It's also supposed to be highly adaptable. In other words the compound can be easily changed to give specific chatacteristics to the rubber for a given tires intended use. If you want to slurp the "coolaid" go here, http://www.conti-tyres.co.uk/conticycle/news_int_5.shtml#01 . Just keep in mind this is "manufacturer hype". The MK hasn't been around long enough to substanciate all of the claims about Black Chili yet. But so far the product has been standing up to the hype.

Good Dirt

no problems on either, although , like mentioned above, lots of shaking and foaming before its ready to go

I've got a set of supersonics tubeless on Stan's Flow rims since September. Similar comments to above: several days of shaking to seal them up, but good since then.

I'd be scared to to tubeless conversion using supersonic. I have a set of Speed King supersonic I use with tubes, the side walls are paper thin.

CupOfJava: You're right, the sidewalls are thin. The trails I ride have no sharp rocks, and I'm not a basher. So far I've had good luck. I like light, high volume tires.

OP: yes, they should work tubeless.

I mounted some MK Protection 2.4's with stans no problem at all. In fact they hardly had any sidewall leaks.

Another thing to consider, is that the Mountain king protection 2.4 is acutally wider than the Mountain King tubeless 2.4. I think it's about a tenth of an inch, but is noticeable and would make the tire handle differently. The protection version acutally measures about 2.3 inches and the tubeless version measures 2.2 inches.

It might eventually work, but I am sick and tired of trying to get the sidewalls to seal with Joe's. After a month of inflating, laying it on the sides, shaking ect, the sidewalls still ooze white stuff if I inflate it over 2.5 bar. I tried it with the Mountain King 2.2 Protection.
If you ask me: If you want to ride a tire tubeless, buy the blooming tubeless version. My Race king 2.2 tubeless is 100%.
