Was it a bad idea to run my Specialized Butcher SX tires tubeless???

...Because I'm starting to think it was. They are the 2.3 variety -- though they measure almost as big as some 2.5's. They came on my 2012 SX Trail, and a buddy of mine recommended going tubeless. So I set them up with a Stans kit. Mostly, it's been a positive upgrade. However, I've been surprised how many holes I've gotten in the tires.

Last night I was careening down a section of a local trail that is very fast and features a couple doubles down a fairly steep grade with a sharp bermed corner at the bottom. Normally, I FLY down this section because the berm will catch me at the bottom. Unfortunately it's fairly rocky as well. On the last double, I must have hit a sharp rock upon landing and it pretty much immediately deflated my front tire. I had time to scrub a little speed but by the time I got to the berm I saw that I no longer had a tire on the rim. I was still going very fast. Needless to say, I ate it HARD -- worst crash I've had in years.

I'm a little leery of leaving these things tubeless. What really concerns me might not be the tire's fault, but the fact that they fit very loosely on my rims. I don't even need tire levers to take them on and off -- it's very easy. Could that be why the tire came off the rim so fast? Also, is it normal to get so many holes in tubeless tires? Most of them have sealed up if I stop and rotate the tire, letting the Stan's goop seal the hole -- but this situation has left me very gun-shy. Please advise...

i'll follow this thread with interest. What pressures were you running when you set off? Any burping down the route?

Are they single ply?
If not, keep the tubeless set up, but save the Butchers for the rear. My dual ply butchers seems as reliable or better than my Minions.

I ran Nevigals tubeless on my Syncros ds32's for 3 years with a burp here or there, but no significant loss. The tires always needed air before a ride it seemed. When I changed to Panaracer Rampage 2.3 the nightmares began. When the first one finally seated after about an hour of trying with 3 of us. I only went to 20psi and shook it around. It was on the floor for 2 minutes and BOOM! Stans everywhere and the tire was a foot away from the rim. The tires fit VERY loose. My Nevi's could come off without levers too, but these things wouldn't even sit on the beads. Two weeks after mounting the Rampage I was riding Moosic, a real rocky place. BOOM! Tire blows off. Stuck a tube in it. A week later I'm blasting down Blueberry at Moosic same outcome but on a strait away without rocks. I went back to Kendas and even though they're loose, I haven't had an issue. Yet...

I think that the ghetto tubeless way with a tube sliced might work for your riding style better that the Stans way. EC

ive run my hillbilly DH tubeless for a year and never had any issues. Im just about to try a pair of Butcher SX tubless and will let you know how I get on too. Probably circa 25psi +/- 3 I'm guessing. 240lb rider kitted up and 2.3 tyres.

I'm removing the Butchers from my bike. I rolled a tire off the rim this weekend 1 min after I had just put 30psi in the tube...and the tube was still inflated!! Whole left side of the tire was off the rim with the tube flopping around like a big tumor. A minute later the tube exploded on its own (probably got scraped). This was with an EX721 rim. Apparently that rim causes quite a problem with the Specialized tires. These are pretty new tires too. Less than 5 fairly easy runs in on them.

Guess I'm gonna bite the pillow and go Maxxis again...ugh.

#1, what rims?

#2, I think you'll find a fairly consistent opinion on here, that unless you go with a proven UST rim (Mavic 823) and a stiff, solid sidewall (proper DH casing) tire, that tubeless isn't great for "aggressive gravity" riding.

What you described sounds to me like where the limits of tubeless are (steep, fast, hard landings, high-g corners).

For me, that type of riding is done with dual-ply tires and tubes. end of story. for me.

I think the problem may be your tires. The SX tires are great in theory because the 1.5 ply is supposedly tough enough but still considerably lighter. The light aspect is true enough, but I just find that the casing doesn't stand up to aggressive riding in rocky conditions. I tried SX Butchers and Clutches, and was initially thrilled because they have the same gripping characteristics and are way lighter, but I eventually tore huge gashes in the tire or blew up the sidewalls on each tire. And this is like after 2 days of resort riding. I've had zero problems with Butcher DH tires or any Maxxis DH tire, and I run everything tubeless.

I heard tubes will give you the Aids. You don't want the Aids.

It makes my brain hurt every time I hear "fits really loose" and it isn't followed by "threw in a tube."

^^^ this.

The fact alone that they fit loosely on your rims is an issue.

I have a gigantic '2.5' speshial ed chunder SX on a dt 600 rim with rubber Stan's strip. A bitch to get on there but has never burped.

I should specify that my issue was with the DH casing, not the SX casing. I didn't know what their designations were until I looked into it.

My rims are Roval DH, and here is the exact tire model (can't tell if it's dual-ply or not -- they're definitely not as stiff as traditional DH-casing tires): Specialized Butcher SX, 60 TPI, aramid bead, soft dual-compound, 26x2.3" Specialized Butcher SX, 60 TPI, aramid bead, soft dual-compound, 26x2.3"

Not to sound like a badass or anything, but I do ride VERY aggressively; push the corners and charge hard no matter what the terrain. I've never had a tire blow off the rim like that. With tubes, I've double-pinch flatted with weaker tires -- but I still had a few seconds to scrub speed before they were completely flat. Not so this time. If there had been a large tree there it could have been MUCH worse, perhaps fatal at the speed I was going. I got lucky. I think what you're saying is wise, and I ought to go back to tubes. Also, I'm a 205ish pound rider with gear, so the amount of force generated in some of my cornering is significant to say the least...

My buddy and I had been sessioning a section of the trail above this point that features an "S" berm where you jump out of one berm, turn in the air, and land into another berm. We each did this about 6 times before continuing down the trail -- I suppose I could have been burping some air every time on that. I started the ride with about 28-30 psi in both tires.

I heard tubes will give you the Aids. You don't want the Aids.

It makes my brain hurt every time I hear "fits really loose" and it isn't followed by "threw in a tube."
Yeah, the "fits really loose" factor is, I think, the major culprit here.

Wait, you've got a tire with multiple holes, and that's blown off the rim a few times, and you're asking if you should keep using it?

Fvck no!

Throw that thing in the trash. You're going to kill yourself.
Well, the front tire only has one hole which I'm sure occurred immediately preceding this crash. It has never blown off the rim before this. Heck, I've only been riding these tires for a couple months. I agree about the "killing myself" assessment, however. I can't have that happen again the way I ride.

You guys have convinced me to go back to tubes -- at least until I can get tighter-fitting tires with burlier sidewalls!

Sorry to hear about your crash. I would definitely return to tubes in your case. Neither the Roval DH rims nor SX tires are endorsed for tubeless. Trying to make either work in a tubeless setup will always be a gamble, more so when using both together.

How big are these holes you're getting? Are we talking pin-pricks or bigger rock gashes?

The holes (gashes, really) I'm seeing are 1/8 - 1/4" long. The Stan's compound seals them up if I rotate the gash to the ground. We don't have thorns where I ride, so these are caused by hitting jagged rocks.

I talked to the guys at a local bike shop and they recommended that I really need UST tires to be safe running tubeless.

No just ust rims that aren't made by stans.

Any DOWNHILL tire will work tubeless with sealant.
What he said. UST versions of tires are pretty flimsy. I've had terrible luck (torn sidewalls galore) with Maxxis UST tires.

Okay. If you're cutting through SX tires, the next step up would be DH casings. You would also gain some better retention during flats.

I agree with everyone else though that UST tires don't make as big a difference as the rim does. UST tires don't necessarily fit any tighter than non-UST.

I'm not a big fan of tubeless on big bikes, but if I wanted to run tubeless with aggressive tires, I'd try our DH tires with 823 or similar rims. That's the only combo I've usually heard of having worked for others (still no guarantee that it will work for you).

I would too but running a sticky rear tire in dry ass california/arizona/nevada/new mexico/montana/idaho/southern oregon/eastern washington is a waste of money and momentum.

It's like every other tire company just sits there and goes 'hey maxxis, here's another one who's money we don't want'

You guys make some good tires. Now just make ONE that rolls fast.

No kidding. It can't be THAT hard to match their performance and not infringe on any IP.

If someone made a High Roller 3C knockoff that didn't cost a kidney and had the same casings, I'd buy a ton.

Some company has got to realize they could rake in 2-5x more sales with a bit slimmer margin on what is essentially the same tire, and make more money at the end of the day.

Using Stans Strips? Some tire/rim combos require a few layers of tape under the strip to fit and seal well.

I'd be happy if anyone else just still made a damn 60a dh tire.

We can build them. We have the technology. We just need a couple thousand more of your friends to demand them in addition to (not instead of) the DH tires we already sell.

I really do understand where you're coming from, but we just haven't seen enough market demand yet. DH tires for us are not a "if you build it, they will ride it" category. We have to listen to our racers, dealers and customers to figure out how much demand there really is before we can produce a new model.

Correct me if I'm wrong but you guys don't even make an sx/genuinely tough casing/UST tire that is a 60a durometer. DH or not, this sticky tire bidness has it's place but it has become a little too all encompassing. A hard compound butcher would do (let me see if I can say this without puking) the emerging enduro market some good.

And for FWIW, almost everyone I know runs a hard compound dh tire in the rear on their big bikes. They all have the same logo on them not because of any kind of brand loyalty, but because there's only one damn company making them.They'll sell, gwin just needs to win a damn race. I know just making something good doesn't mean it sells (see chunder tread for reference), but that's partially on your marketing department's shoulders.

But you got me curious. What's the fast rolling dh casing tire you make that is fast because it's a hard compound, not because it doesn't have dick for center knobs?

The demand for a Maxxis 3C DH caliber tire at ~$50 MRSP, $30 wholesale would be through the ROOF! People run DH tires MUCH longer than they probably should because they cost more than moto tires. If high end DH tires were $50 retail then people would be replacing them 2-3 times as often I imagine.

Economies of scale or not, I still can't wrap my head around the fact that my rear maxxis DH tire costs as much or more than my maxxis rear moto tire which has about 10 pounds more rubber and steel and must cost 2-3 times in shipping costs alone just to get it overseas.

There's NO way higher production volumes account for that difference. There aren't THAT many quantities of a given moto tire model being purchased compared to a given 3C DH Maxxis tire.

All the moto tires are basically priced the same these days, +/- 5-10% at MSRP. The high end Maxxis DH tires are in the same ballpark as them.

Intense tires maybe?

I'd like to re-affirm sentiments already echoed in this thread.

Despite reading on RM not to run the Butcher SX tubeless, with people saying that it is dangerous, I decided to do it anyways. Well, it didn't work out. I blew the rear off the rim at 35psi landing a little sideways on a hip jump. "Ok, it won't work on the rear, but the front should be fine". Wrong again. The very next ride I overshot a double that had a berm after it so I was leaned over a bit. Blew the front at 35psi off and ate ****. Now I'm out for a week or two.

Learn from me, unless you're riding mellow AM and staying on the ground, don't run SX casings tubeless!!

^^Thanks for the extra support to my decision. I will NEVER run Butcher SX tires tubeless again. NEVER. I've been gathering info from bike shops and people around town and I'm led to believe the biggest problem I have with them and my rims is that they fit WAY too loose. I don't know if the tires err on the big side or my Roval DH rims err on the small side or both, but the general consensus is that if you're running tubeless for DH, the tires had better fit TIGHT.

As you and I have both found out, it's not a "worth the risk" kind of decision. My riding has taken a huge turn for the worse now as I am paranoid about my tires blowing off the rim. It might take me all summer to get back to the level I've been for 15+ years. Scary stuff.

I think using cut tube for tubeless is the best solution.
