Lower Your Air Pressure In Your Dirt Bike Tires! 

I am light (70 kg) and not very aggressive riding. I absolutely love the TUbliss, generally at 4 PSI. I tried a soft Michelin mousse, but didn't get the required traction. TUbliss at 3 or even 2 PSI is exceptionally good in muddy uphills. Feels like having a magnetic rear tire! Thanks Megs!

I'm a big dude, 290lbs and I ride a 2019 yz250fx recon hybrid gummy a size larger than stock and I run about 10lbs in rear with a HD tube and a shinko fat Tyre on front one size larger than stock with around 13-14 lbs in it, mainly bigger tires for more cushion on rocks and roots and I have great traction, I also have a 53t sprocket on back to give me just a little bit more low end, I love my 4t on trails and rocky hill climbs and my clutch control has gotten really good, Meg you inspired me to really work on and practice clutch control, thank you

YESSSS Excellent advice. You don't even need a Tubliss system or mousse, just use heavy duty inner tubes. I'm a 200 pound man and I've been riding trails for years now with about 9 psi front and 8 in the rear. You just can't carelessly slam over sharp-edged boulders going 30mph. You can tell when you're compressing the sidewall all the way and when you aren't. There's a feel to it and you get the hang of it. I've never bent my rims or had a flat or had anything bad happen. But those low squishy tire pressures are absolute MAGIC for your traction. You've got almost double the traction if you run low pressure plus nice soft gummy tires, compared to rock-hard tire pressures and stupid motocross tires. Get yourself a set of Tusk gummy hybrid tires. 90/100 front and 120/90 rear. Let that sink in: double your traction. Not only that, if you have a bike with too-stiff damping or old-school damping rod forks, that low tire pressure style of riding will make the bike much more smooth and pleasant to ride too. Low tire pressures eat up vibrations and trail chatter like washboard surface, small rocks, roots and other small sharp things in the trail.

I run a vacuum in my tires. Negative psi ftw

Great info, it’s amazing how many folks I run into that don’t know it. Sometimes this is the last piece someone needs for a breakthrough. I usually run around 10 front and rear, and 8 in the more rocky stuff with tubes. Honestly never considered rider weight, I just found what worked for me. Your riding is looking more and more effortless 🔥

Hello Meg's you legend! Just sharing my experience with air pressure with you to share if you like. I ride a 450exc and a 200exc for more harder enduro ,I run mitas tyres on the 200exc and goldentyres on the 450exc. On both bikes I coat the inner tubes with either moose lube or rubber grease . This allows the inner tube to slip instead of pinching when hitting a hard rock or tree root. I have successfully run this for a number of years now down to as low as 3.5psi but I usually run about 5psi on the rears and haven't had a pinchflat since adopting this system. Certainly not the be all and end all ,but it certainly has worked for me and at 110kgs the tyres certainly do squash down over obsticals. Once again your a legend and play a huge role in helping me to get my lady and her 2 children riding and safely. Thankyou

I've been running 8psi with a Bridgestone UHD tube for over a year in a 220 Ride semi-gummy. Works great in the nasty. Normally run Tubliss front and rear but lost the rear bladder and couldn't find one anywhere at the time. So, I installed that tube to get me through until my next tire change and have just kept using it.

Love this advice,,,you are so correct,,low psi=traction,,,love my mousse set up ,,,soft in the rear,,,hard in the front,,,not worried about the hard hits to the front ,,,and never worried about the traction or deflection of the rear of the bike,,ride way too many rocks in Pennsylvania ,,,love the video,,,Happy holidays

awesome tip. for hill climbing/winter riding on my ttr i drop my rear down to 6 psi, when i had my tire changed at a shop they told me i'm crazy and it was "flat". if i'm on a heavier bike like my 250f i usually keep it around 8-10 👍

Such a great tip! you still see so meany people running way too much pressure. For those on a budget 4mm thick tubes covered in rubber grease is a good option, I'm 90kg in riding gear and I run 2.5psi in the rear using them. I ride mostly slow tech like rocky creek beds and have only had one pinch flat in the last 11 years.

Great slomo. Convincing shots. Thanks, much aprreciated. Günter/Nürnberg, Germany

Have been using Lucioli tubes for a month now and so far all good for trail riding.8 in the front and 5 psi in the back;still experimenting.Only negative is the weight being 7 mm thick;but that being low down often feels good;planted feel.But no more punctures.

Spot on! I think it is worth mentioning that you have incorporated a mousse with your tubliss system, which allows to run near 0 psi with a lesser risk of damage to the tires/rims

Thank you!!

I usually read the book it comes with. Tells you what's best. I like making rutts. Harder the better.

Running low pressure is the key of traction, but if you dont use tubliss just only hd tubes you gonna cut the valves so you need two rim lock for safe.

I try to keep the pressure in my ass low. That way, it can grab onto the seat better in those knarly situations 👍🏻

Tell us about front too! i'm just starting my off road fun after decades on the street and track. Started at 22 PSI, down to 17 PSI, but running tubes and no rim locks. 160 # w/out gear and mostly service roads, nothing gnarly.

Thankfully it's a lot simpler than what tyre pressures to run in super bikes! LOL Cheers from Australia...)

I've gotten away with 7 in the front, 11 in the rear with Dunlop 606's on my DRZ road and trail riding, I weigh 170, and put up to 50 lbs of gear on the back and seldom get flats! It's got a real stiff side wall!

Tubliss with 2lbs IRC m5b does magic

Can you show us the half nitromousse? what does that look like? I never heard of it. What do you suggest for riding on desert sand?

in my wr155r cc I run on a tube in 6psi rear and 11psi front tire

very good

Any videos on how to install a tubeless system would be great.

im 240lbs i run 10-15 depending on season and tire choice

What PSI do you run in your front tire?

Hello Meggs, I am writing to you from Russia, you have amazing videos, and excellent riding technique.. I bought my wife a motorcycle, and she is short, 164 cm, and how tall are you?

140 lb rider before gear, 10 psi with heavy tubes for FL Hare Scrambles and even moto.

At 1 .5 or 5 psi have you bent your rim at this psi ?

Did you glue the tire to the rim ? Or not need to do that ?

What is "half a nitro moose"? The link doesn't show up in my device

How do you get a moose in the tire?

Question. You say you run half of a nitro mousse. Please explain.

Need to lower mine (from 9#). Thanks. How about the front tire?

What do you mean by half mousse setup? You mean front is mousse?

Plushie Nitromousse and a decent tire = tons of traction, no worries. 150 lb rider on 300 two smoker.

Megs, why don't you ever use a trials tire?

"Megnatic" rear tyre. You read it here first. :)

Isn't hitting a rock and denting your rim a concern with that low of air pressure? I ride in more open areas at higher speed so I'm thinking I probably need at least 15 psi. I hit softball sized rocks when I'm riding whoops all the time. This isn't at a track. It's at an ORV Park that just happens to have some whoops and hill climbs.

How do you run 1/2 a nito mouse with Tubliss?

Can you expand on the "half a mousse". Do you mean one wheel has tubliss and the other the mousse?

Until I get my YZ250 back I have been trying to do this on a CRF450RL with DOT Dunlop D606. Not sure this is the right tool for rock climbs lol.

grease your tubes with red rubber grease. zero pinches. Period. Don'y use tape or other to protect inside bead rim. Use a MTB tube folded on itslef with of course valve vcut, folded on itself and greased : zero water and shit going inside by spokes screws, aloow tube to stay in place. Two trick which can make you ride a simple tube at 0.3 /0.4 bars all time.(4.3 psi) No use of big UHD tubes : if something can go through your tire, it will go same in a 4 mm rubber one. than in a 2 one. Pain to change, nearly impossible to patch except with vulcanization, goes in pieces in heat and fast ride... RRB , simple tubes, mtb tube rim bead protection Try it ;) Good rides !!! And two rim locks of course ;)

Yikes. I think I’m running like 22psi.

run mousse: be happy

If you're aggressive enough and if you're running with a tube...you'll pinch it..

What about a dented rim, has that ever happened to you?

Why don’t you race some of the hard enduro races ?

6.9 psi 😂
