In my riding clinics, we go over tire setup in the morning. The most common question I get asked is "How much air pressure should I be running?" I find that most of the people in my class are often running more air than they need in their tires. I wanted to address this in a video in hopes that it helps some people! This is especially important for the smaller/lighter riders but it still applies to all riders.
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
Even flat on the top!
Just don't deflate them too much unless you're riding in Australia. If you are, you need the suction to keep from falling off the planet since you'll be riding upside down. 🤠
@@eljuano28 You are correct sir!
I’m on the lighter side (160lbs/72kg) and I routinely run 1-3 pounds in the back. Here in Hawaii we have plenty of greasy muddy :)
Helps also when riding on the moon on the Marius Hills! 😅
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 🔥
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
👍
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
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.
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.
i'm using redrubber grease for 4 years now with simple tubes. zero pinches, 0.4 bars all time. two rim locks mandatory . ( and rim protection with greased folded MTB tube valve cut ) Sadly lots of people don't know this simple fact :-( I gave up 4mm as they are nearly impossible to patch on the way , except by vulcanization. On fast laisions in summer they are fast destroyed too and won't prevent flats, as any thorn or object going throug tire carcass will easily go through tube whatebver 4 or 2 mm thickness. sorry, it always made me smile ;)
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
Yep, I mentioned that right away in the beginning a posted a link to a more detailed video about the half mousse. Thanks for watching!
Great slomo. Convincing shots. Thanks, much aprreciated. Günter/Nürnberg, Germany
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.
two rim locks all the time ) and easily better balance
I usually read the book it comes with. Tells you what's best. I like making rutts. Harder the better.
Thank you!!
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.
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!
I try to keep the pressure in my ass low. That way, it can grab onto the seat better in those knarly situations 👍🏻
🤣🤣🤣
Thankfully it's a lot simpler than what tyre pressures to run in super bikes! LOL Cheers from Australia...)
Any videos on how to install a tubeless system would be great.
Tubliss with 2lbs IRC m5b does magic
very good
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?
in my wr155r cc I run on a tube in 6psi rear and 11psi front tire
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?
140 lb rider before gear, 10 psi with heavy tubes for FL Hare Scrambles and even moto.
im 240lbs i run 10-15 depending on season and tire choice
Did you glue the tire to the rim ?
Or not need to do that ?
At 1 .5 or 5 psi have you bent your rim at this psi ?
Question. You say you run half of a nitro mousse. Please explain.
What is "half a nitro moose"? The link doesn't show up in my device
Plushie Nitromousse and a decent tire = tons of traction, no worries. 150 lb rider on 300 two smoker.
"Megnatic" rear tyre. You read it here first. :)
How do you get a moose in the tire?
What PSI do you run in your front tire?
Megs, why don't you ever use a trials tire?
What do you mean by half mousse setup? You mean front is mousse?
I understand that she cuts a mouse in half in such a way that installs the half contacting the TUbliss and rim.
She has a video on this technique
No, I run half of a mousse in my rear tire with the Tubliss. The link to a more detailed video about my setup pops up within the first 20 seconds of this video.
Need to lower mine (from 9#). Thanks.
How about the front tire?
It usually is less beneficial to run less because it will wash out and slide.
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.
The tubliss system stick out further then the sidewalls of the rim protecting them with 100psi, and she also runs the outer half of an old mousse to protect the tubliss system and rim even more so it's pretty safe. Personally I run a tyre with a really heavy sidewall to protect the rim.
Can you expand on the "half a mousse". Do you mean one wheel has tubliss and the other the mousse?
Check out my more in depth video on tire setup! I go in more detail with this. There’s a link to it within the first 20 seconds of this video I think.
@@megs_braap Watched it. Good stuff. Thanks for all great info. Keep it coming.
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 ;)
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.
By saying, "not the right tool" you mean the 450f ---right? (lol).
@@brianpolen1087 no I'm turning that crank to 11 it's the CRF 450 RL dual sport
How do you run 1/2 a nito mouse with Tubliss?
Yes, I am curious about this also. Megs?
She has made a video on it somewhere. Basically she cuts out the inner half of the moose leaving the outside hoop, then shoves that in the tyre before mounting it onto the wheel and TuBliss system.
If you're aggressive enough and if you're running with a tube...you'll pinch it..
Yikes. I think I’m running like 22psi.
run mousse: be happy
What about a dented rim, has that ever happened to you?
I’ve never had problems with denting my rims. I am small but the top pros in the hard enduro circuit are way bigger than me and hit things pretty hard. They run low pressure as well.
Why don’t you race some of the hard enduro races ?
I raced one a couple of months ago. I raced the Grindingstone hard enduro in Page, AZ. I don’t normally race because I rely on my clinics for my income. So I can’t risk getting injured during my clinic tours.
Don’t blame you for not risking it. Didn’t realize you taught so much. I’ve been trying to work up to doing a hard enduro eventually
6.9 psi 😂
