What happens when you race on a tire with 0 PSI?

While racing KOM my tubliss went flat but I pushed on at 0psi through the the 6 hours/ 60 miles. This is what the tire looks like after the punishment!

I use those single green stripe mitas tyres with a nitromouse in them. No complaints. Good grip and durability 👍

[@WhiteEagle114T]

Great vid as always my man. I did cringe when you didn't take the tubliss insert and inner bladder out for cleaning before reinstalling the tire though. I've been running Tubliss in the rear, with zero issues for about 3 years now. Absolutely love it. BUT... if I get a flat and any dirt at all gets inside the tire, I always remove the inner liner and HP bladder to clean all the dirt out thoroughly. If there is any dirt, or worse small little rocks, in there... there are two possible issues: 1. After installing the new tire, you could end up with a slow leak because the there is dirt between the tubliss liner and the tire bead... which is super frustrating. 2. If there is enough dirt, or a small rock, that gets down in between the rim and the inner high pressure bladder, it could potentially cause a rupture in the high pressure bladder and cause catastrophic failure. ( I've never allowed that to happen in the rear, but it happend to me once in the front, and ended my ride) I love Tubliss in the rear. Primarily running with heavier walled tired like the M5B. Good experience with VE33S Gekkota too. I did run it with a Kenda IBEX gummy in the Virginia City Grand Prix once also, as an experiment, at 10 psi, and it felt great, and had no damage to my rim. Totally destroyed the gummy in that kind of fast, tire spinning, race of course though.

[@TrailBoundco]

WhiteEagle114T Jeremiah Goulett I think I got lucky because this new mitas sealed up super well and have had no issues with air slowly leaking out like the M5b did

[@evanjohnson5480]

You get my vote for durability tester of the year my friend. You definitly dont hold back on your equipment.

[@BraaapoholicBob]

This is the same combo I have been running M5B and Tubliss. Coincidentally I have a home just across highway 247 from Hammertown and do most all my riding in that area. I have to say that your video is an excellent overview and a great advertisement for Tubliss and how amazingly strong that system is. I tried running bib mousse and quite frankly I don’t know why anybody other than a professional racer would want to run a Mousse. No system is perfect of course but having used both I feel Tubliss is far better for the average rider. The advantages of Tubliss are so many including weight, feel, adjustability, proper suspension working, etc. Keep making these great vids! And yes...are you insane??? That tire is DONE!!!

[@vrock265]

In my opinion Tubliss saved the day for you. And it is still working. You should have taken it completely apart and cleaned it. There could be abrasive material in there that might cause a failure. I run tubliss on all 3 of my dirt bikes, only had one failure and that was last week due to a Pirelli bead wire breaking off and puncturing the inner bladder tube. Pictures in my IG.

[@atiimtau]

In my experience, Tires with Soft sidewalls just dont gel all that well with tubliss. Tubliss seems to work best on tires with some stiff hold up if you run them super low, like the VE33s or GT333. The IX-09W is a better tire with a mousse over tubliss, for me anyways. I had issues with that carcass holding air on tibliss....

[@CW-up7xv]

He ran an M5B which has a stiffer sidewall than the tires u mentioned.

[@TrailBoundco]

OaktrekX yeah the M5b wasn’t holding air to well, always having to pump it up every weekend as it would slowly leak. This new mitas holds air perfectly though, way less maintenance

[@CW-up7xv]

@@TrailBoundco it shouldn't slowly leak. In that case spray it with soapy water to find the leak and plug it if you can. I've been running the m5b with tubliss for a while and I've never had any leak issues I couldn't plug!

[@f18a]

I agree 100% with your overall point, but I consider a GT333 medium stiffness at best. It is firm enough for Tubliss but I think a Shinko 505 is a better match (even though the 333 is an otherwise superior tire).

[@senor7857]

The best tyre for slippery rock it is mitas ef-07 2 green stripes or 1 green stripe. C18 sucks in those conditions.

[@sloppytaco9629]

That's a good lookin wheel ya got there Willis!!!!!!!!

[@seanmclaughlin1428]

Trashed a rear tire when I punctured a kenda equilibrium out on the trail. Also trashed the tubliss from the road ride back. Went to bibs now.

[@MitchOfCanada]

boobliss, bib and tubliss, ultimate combo

[@MichaelAbramo]

IRC M5B in NJ Pine Barrens. Sandy woods/whoops and loam, running 8psi with tubliss. Love it. When I rock ride I switch to a Kenda IBEX 6psi tubliss.

[@TrailBoundco]

Michael Abramo nice! Those Ibex are sticky but don’t last long

[@janvalvoda7792]

for enduro i recommend Mitas xt754 green stripe its good traction ,and on my bike it works 50hours

[@joemaynard5551]

Hey there. I really enjoy your videos and your a heck of a rider. I run tubliss on my bike and my sons bike. He has gotten a good bit faster than me and i will have to move him to bibs. I called and spoke with the guys at nuetech before i bought tubliss and he recommended the shinko 525 cheater due to the strength of the sidewall and we have had pretty good luck with Kendas but haven't tried their gummies. For what its worth we live and ride in North GA... rocks, roots, snotty red clay, dust over hard pack. For you, i think your speed means you need to go to the bibs. Tubliss is great for us slower riders but your speed will be a little more than they can handle. Also, 0 psi can bite you as you found out. Keep up the great videos and riding. Cheers

[@TrailBoundco]

Joe Maynard thanks man I’m actually pretty slow, I like riding as slow as I can! Does the 525 hold air well or after a week does it leak out a little?

[@joemaynard5551]

Trailbound co Hey Trailbound. My last ride was the last Sunday in January. I just went to check psi. I set my tire with 7 to 8 psi that day and with the check I just did, it was at 5.7 psi. Some leakage but it’s been over a month. Acceptable for me. I mountain bike with tires set up tubeless as well and they leak down faster. Even using Stan’s no tube liquid for the mtb tires. It may be influenced on the amount of soapy water used during the set up. Hope this helps.

[@jessarellanes6648]

You been making some good videos lately, keep up the good work.

[@maucina12]

Here is a great tip for tubliss. Pour about half liter of soapy water inside tire so it is always wet and slippery. You will completly avoid any wear from running tubliss with flat tire. Everybody does it in europe for hard enduro.

[@jordanouzts1762]

I ran the tubless with a dunlop at81ex at last year's TKO and got a flat at the beginning of the first race of Sunday and was able to compete the entire lap without the tubless failing. Also I was riding a drz400 witch is around 300 lbs. So in my experience the tubless system is pretty resilient.

[@AlSoul7023]

Neutech nitro bib front and rear 100%. After a ride breaking them in , they feel just like a tube at 12 psi and only get better. I’ve got 40 hrs on mine and LOVE them. I don’t ride in the granite like you but we do have a lot of rock cobble and loose shale up here in far nor cal. Come run Shasta Grand Prix this year!

[@NWDirtbiker]

I really like the Maxxis desert IT with tubliss. I run the 120. Side walls are stiff so no problems going very low on tire pressure.

[@dylcar]

“Good lookin dirt though” 😂

[@Towing417]

What came out of the tire is rubber from the tire running flat. When its all the way flat the tire flexes way past its limit causing a ton of friction and the rubber falls apart inside.

[@BAYAREAMX]

A 130 is actually a 110 and a 140 is actually a 120. They just measure knob to know where most tire manufactures measure in between the knobs.

[@kiapyro]

I feel like whenever you run 20-30 miles at 0 psi on a tire they are pretty done even if you can air them back up. It's like the side walls loose all their stiffness and they don't feel right. The last tire I ran flat for 35ish miles started to separate between the sidewall and knobs.

[@cobuz29]

i use the same tubliss system for 200 hour in combination with Mitas EF07 double green stripe and single green stripe and never had any problem, the tyre will last 20-30 hours depending on the terrain you ride but never had any issue with the tubliss system, i always have car tyre plugs and a small hand pump in case i have a flat tyre but never used them, I also tried mousse in front and back but didnt like the feel of the bike

[@jackrussell9744]

Awesome race report. Tires are a consumable in racing bro. Spend that money.

[@premixpeter1972]

I'd definitely recommend the 130/80 size for your next go with the M5B EVO. The 130-140 sizes use a significantly softer compound than the 110-120 sizes that's in my opinion much more versatile. The 130/80 size is also comparable to a 110/100 size just with taller knobs. A 250 2 stroke will pull a 130/80 M5B evo, albeit with less wheelspin than normal. As far as your question at the end of the video, the Shinko 216MX/SX 140 fatty gummy rear is a no go with tubliss. The carcass is just too soft/prone to tears.

[@vincelee8937]

Chris, a public THANK YOU again for that tow back in thanksgiving, and letting me ride your bike out instead of having to double up, SOLID dude, apologies for my beta failure, (cdi harness burnt up). I have a choice btwn the stiff feeling GT333 (never run it) and M5 this weekend w/a chance of snow in the Utes, which do you think would be better w/ tubliss?

[@mikewhitcomb6558]

I've run plenty of D37 desert races on a flat before I had enough and went mousse. I always double rim locked my rear and I could pretty much run at race speed. In fact I got a rear flat in the first couple miles of a time keeper enduro and was still able to zero the loop and change it out for the second loop at the break. That being said, the tires were junk at the end, and unfortunately they were usually new of course :(

[@infidelmat]

Lucky that the bladder didn't get messed up, or the tire completly fails (I had my inner bladder shoot out the tire after the rim lock failed after 40km). I found some tires don't run flat well at all (Shinko 505 525, Kenda Ibex) due to softer sidewalls, where dessert tires (like At81RC) are stiff enough to support the tire.

[@TrailBoundco]

Oh interesting! Yeah got lucky it held on the whole race

[@infidelmat]

@@TrailBoundco yeah, also flat is different from 0 psi, because the later still keeps the tire supported, while the former allows the tire to completely collapse. Sometimes I would run the At81Rc at 0 psi but air it down on the stand, so at least there's still an air volume.

[@weekendenduro1111]

for you is mitas TERRA FORCE-EF 140/80-18 GREEN strap

[@quarasisoed1035]

Have a look at the Mitas XT754 It's just awesome in sand with it's 20mm knobs. But it works also very good in the woods. I'm running Tubliss on it all the time and often with close to zero or even zero pressure on it.

[@spacejaime]

I had to look it up - Mitas is a Czech tire manufacturer. Do you plan to test any Goldentyre tires? Always enjoy your vids! Thanks and cheers!

[@TrailBoundco]

Jaime thanks It’s not on my immediate list but one day I’d like to. Do they do well with tubliss? I hear they’re thin

[@spacejaime]

@@TrailBoundco - no idea. I hear they are very popular in the Extreme Enduro circuit ( those guys are real athletes!). Very much in vogue, like the Mitas.

[@chrisfetter8090]

I’m very curious to see how the Mitas do! I have bought one and it’s also mounted with Tubliss..... too cold to start riding here in this part of Canada.

[@spacejaime]

Beautiful mountains here, there and everywhere......I have a big mountain for sale here in South Florida.......oh my, I'm so envious!!! On the subject of trail tires, it's getting crowded and confusing, so many options. Here in Fl., no need for gummy's.

[@bensmith8125]

You should do a van tour.

[@leonvojnovic9647]

[@enduronorthnz6437]

thats not bad , ive had the knobs go through the red liner and that was in a extreme enduro race

Dude, that’s a badass intro! 🤟

[@seanwahl1000]

It's my go to for the mud.

[@adxtriple]

Seeing you at Hammers this year? Just installed a 120/100 shinko 525 cheater probably run 4-6 psi and a 90-100 shinko 216 cheater and thinking around 6-8 psi with tubliss. Not for racing, just bombing around the desert and canyons. Thoughts?

[@budgetendurogroup9635]

For any enduro race that is extreme run a soft 120 mouse with 140 metzeler tyre and two bead lockers

[@power.turbine4872]

It looks like you might only need 2 different mousses for the rears you run. Double rim lock it and you won’t regret it

[@TrailBoundco]

power.turbine Maybe, about to get a 140 though so that’s another size

[@power.turbine4872]

Trailbound co would give more content 🤓

[@georgepurchase9865]

if you run at zero pressure the inner-tube will fail eventual as you end up riding on the pink liner this causes alot of friction and the inner tube fail were it passes through the rim lock..... talking from experience. tubliss is reliable as long as you dont run too low pressure that it runs on the pink linner

[@highsnburgers4862]

They way you ride, chug, chug and up the cliff he goes...setup a some race wheels (maybe from your spare bike) with the 120/100 Ibex and a soft Nitro mousse on both ends. No pump, tire plugs, glue, tire irons, or air gauge to carry. Less = more. Tubliss is cool for most riding but it can fail in competition and it's too weak for hard enduro racing at your level. Tire failure is not an option! LOL Good luck!

[@twmuis]

I did I think it was a 65-70 mile desert race with a front flat with tubless on it (I got the flat cause I didn't install it right), but I re mounted it, added slime and haven't touched it since! Probably 35-40 hours on that front tire. Needless to say it's time for a new one lol 😆😂

[@nvmcrider8475]

If you're loading up and spending the money to go racing, get the mousse. If you want a soft feel use a well worn mousse or drill some holes in it to soften it up and you will never have to worry about a flat. A flat gummy with the tubeless system is going to be fishtailing all over the place.

[@dontforgetnomemories7329]

Did you use tubeless tires for the front wheels too?

[@russianrouletteracing]

An unrelated question to this video: when are you going to have the bags in stock?:)

[@markwilson8811]

WTF! I if your goal was to make Tubliss look bad you did the opposite. Tubliss saved your day . 60 Km hard enduro what did you expect your tire to look like?

[@FErdr20]

60miles.. about 100km. Tubless for the win!

[@TrailBoundco]

I don’t think I was trying to make Tubliss look bad it’s more of, what it looks like to run tubliss at 0 psi on a tire

[@kevinclark9176]

Why didn’t you discuss the rim? Looked fairly beat up.

[@budgetendurogroup9635]

I’m from England and have never been able to able to find any tyres you run but most enduro guys over hear run mitas 754 green stripe or a metzeler 6days extreme super soft

[@TrailBoundco]

No mitas xt454 or eh07? Those have been my favorite since I started testing mitas options

[@musicbox4022]

I can’t believe people still joke around with all those tubes (including “tubeless” which ironically contains tubes)- just get mousses and NEVER worry about flats again. They’re light, they’re durable, they’re soft, they’re great feedback... superior technology in every way. It’s almost like people want to get flats. I don’t understand it.

[@WhiteEagle114T]

They are also EXPENSIVE and change quite a bit in feel over time. I still run a Nitro Mousse in front, but out back I like the adjustability of Tubliss, and it's very cost effective over time. I'm still on the first one I bought for the rear 3 years ago. Has over 120 hrs on it.

[@TrailBoundco]

MusicBox I don’t like the idea of them changing feel over time without my say in it. HD tubes and Tubliss have been nice as I change psi all the time for different environments as I drive so much to ride every weekend it varies quite a bit. Moose has been good up front as I keep that pressure constant and same tire every time

[@atiimtau]

​@@TrailBoundco I agree 1000%. I will take a measurable & consistent feel in my tires for my given terrain 100% of the time over just eliminating flats. For a pro racer who can have freshie mousses every race, its a no brainier to run that setup. But for 80% of us average folks, Tubliss just makes the most sense.

[@musicbox4022]

Have you tried them? I’ve tried HD tubes, tubeless, tube saddles, and nitros. I live here in the mountains of Colorado, and the mousse is the only way to go... endless sharp choppy rocks. I was skeptical about nitros too but I will never look back. I should mention I’m a larger rider at 220lbs. Anytime I can eliminate a worry on these gnarly rides.. and still achieve incredible performance.. no brainer. They’re the best thing I’ve tried. The new nitros are much more durable too. One rear nitro lasts me 3 new rear tires. I will gladly pay to never worry about fixing some tire in the middle of nowhere or trying to ride out on a flat... ruining my day, and potentially my whole trip. I also love NOT carrying tire irons and pumps and tubes and plugs and slime and lug wrenches in my pack. Of course, I only get to do 2-3 epic trips per year with 3-4 long days out per trip... so if something stupid like a flat were to ruin my trip again.. what a waste. Of course- I don’t like to bring multiple tires on my trips either. less things in my long camping list, less tools/weight on my back, less tires in my trailer... but perhaps most of all- total piece of mind. Chris- I believe you would have placed much better in that last race had you not been screwing around with your tire... I think you’re awesome and I wanna see you win the shit!!

[@kdshiv]

@@TrailBoundco what front tire are you running?

[@rogeroverout621]

What psi did you start the race with? I’ve run the Tubliss at 0-1psi thru one lap of the Stix and stones A course on a 70% Shinko 505 with no problems. I haven’t seen anyone put the Tubliss thru the kind of torture you did at KOM. If the inner bladder was still going strong after that you should be good at 0psi but just need a bit tougher gummy tire maybe?

[@TrailBoundco]

rogeroverout621 I started at 4-5 and it was a M5b evo which is pretty hard. I feel like a gummy or hybrid gummy would have got eaten up even more. Cody webb ran a kenda track master which is like a dual sport tire but with an ultra soft gummy. He wanted to make sure it lasted through the 3 laps of hell he put it though

[@rogeroverout621]

Trailbound co I was thinking a gummy for RevLimiter. Maybe an Ibex or AT81ex? It’d be nice if you had time and money to test one first though. Thanks!

[@MonsterMotard]

In hindsight, would you have preferred to use a mousse in the race?

[@TrailBoundco]

RoadRac3r I think so, I mean can’t beat the traction! But I don’t know if it was worth the cost of a new tire or that 35 min pit (but that could have been avoided if I felt comfortable just keeping going while flat )

[@colechristensen25]

Chris don’t run tubeless. I’d use a heavy duty tube before I use tubeless. They are heavy, prone to punching and inconsistent. Using tire slime, packing plugs, drilling out your rim, that’s a pain! If you’re racing, run a bib. No one in the professional realm uses tubeless, for good reason. Those who say changing a bib is difficult, have never really done it or don’t know how. Look up the six days guys and they change them in 2 mins. I’m not quite that fast, but they’re easier than tube for sure. I respect you and your great videos! I’m hoping to race king of the motos next year 👍🏼

[@EddiNice]

Wow the world is so small, one person thinks something will work, and at the same time some one is stepping away from the same idea. I ride hard enduro, I run tubliss, and on my 1st race last season I raced KTM 300 with Mitas 1 Green Line & Tubliss and it ruined it, I had the same experience, 10 minutes in the race, then pluged it 3 times and as soon as I needed to be on the pipe to do a hill climb the plug would come out and I would be on a flat. Mitas Green line EF-07 in Europe, is too soft to run 0psi. Since then I only run tubliss on my practice bikes and mousses on my racing bikes. I have a youtube channel, it is in Bulgarian, but here you can see the SAME problem you had but with Mitas and as you can see from the tyre, it is 5 minutes into riding. kzbin.info/www/bejne/mWSmdaB7pr2Mh6c Mital ef-07 works exceptionally well and it is a great tyre. I run in on all of my bikes.

[@Branhamjeffd]
