I agree mostly (I am heavier at 84kg so more pressure as he noted) but my struggle here and with our road bikes is what about the manufacturer minimum recommended pressure? My Continental CX Race tires have no minimum while my Specialized Pathfinder Pro show Minimum 50psi and moreover my wife’s road S Works tires are minimum 100psi (and she is 54kg). Is running lower than the minimum OK?? Thanks
@@streetsandpeaks3013 It's totally OK. The manufacturer's recommendation is simply that... a recommendation. You need enough air to avoid pinch-flats for sure, but once at that level it's up to you to find your preference.
bought a new pathfinders 38 and had my first tubeless ride with around 30psi through mixed forest terrain, and this was a completely new experience. wow effect!
Great stuff, thanks James, this was a great explanation for what to do. I've recently moved to Schwalble Marathon Tour and it's like concrete, so eager to put some of your tips into use.
Really helpful, cheers. I'm new to GRVL having come from MTB/road riding so am all ears to tips & guidance. I ride in north of England so it tends to be wet & muddy so am running tubeless & will tend toward low PSI for grip mainly
Excellent video without useless blah blah and self promotion Really liked the example with the wood I ride a flat bar gravel bike on road and on hard dry gravel without too many rocks or loose terrain Tires 700x38c with tubes, without knobbles and with double puncture resistant, 670gr I use 43F-48R, and if want something more confident off road, I use 38F-43R that has a little bit rolling resistance on tarmac Looking to change to Verdestein Aventura, with these maybe there is no need to drop pressure off road, at least for my preferences
Running 27" 2.25 Schwalbe Marathon mtbs and I find them pingy on ballast gravel anywhere above 30 psi, less than that and they claw in beautifully. Ride the rough, then pump them hard for the tarmac, fantastic do-it-alls
Bought a new Panaracer and it suggested that the min. must be bar 7 and a max of 8. Im really suspicious with the very small range difference but tried it anyway. Yup, it ended in disaster as the inner tube exploded when I pressed the tyre at bar 7 pressure. Perhaps it’s just the inner tube issue.
Hi Paul, good question. It certainly does when running inner tubes (lower pressure = bigger chance of pinch flats), but no real difference when running tubeless👌
Ok, I’m using Gravelking TLC + slick gravel tyres as the name suggests. In a 700 x 32mm. The graph you produced was bang on what I was already using tyre pressures wise. (So I thought the graph must be faulty!) At 200lbs body weight, I put 50 psi. Into the tyres. This is checked every ride. I have to admit to most of my riding being on tarmac and light trails, but the grip is good and I am pleased with ride comfort. Just bought a pair of Pirelli Cinturato mixed terrain 700 x 38 mm. For more adventurous riding, and bikepacking. I’m not sure what TP’s to use. Can you help? Great vid, I have enjoyed it. Thank you.
I’d drop down about 3-5 psi to 45-47 psi. This should feel pretty similar to how your current setup is and still roll pretty quickly on road and harder trails. I actually use the Cinturato M tyres now and I love them. Hope that helps a little as it’s down to personal preference too. Enjoy the ride 🙌
Been a tubeless convert for several years now and ride it on all my bikes; road, gravel, TT and MTB. wouldn't ever go back. Lower pressure and the extra comfort that comes with it is one of the biggest factors for me. Also means I can get away with taking only one tube as a spare, if at all.
I was actually starting to think about going tubeless on my road bike so I could run lower psi for greater grip.. I came off a 20% downhill here in yorkshire and I do wonder how much extra grip I could get with less psi (whilst avoiding pinch flats etc.)
So the side of my wheel has inflate to 50 to 75 P.S.I , But when i pump more above than 75 and reached 215 PSI is it normal for it to reach that higher than the real PSI pressure it was writen side of my wheel
what speed were you riding over that board and how much do you weigh, and the tire width. Thx. I like the bounch colouring, i didn't notice that. I use the sram tire pressure guage, it is close to what i was using, lower pressures. 2.25" width i run under 30 psi. A big thing too for tire squirm is the rim width.
Hi, Really good point! Rolling in @10kph and weighing in at 90kg's (not got my summer body back yet 🤣) Was using 650b 45mm Pirelli Cinturato H's. Yeah the Sram gauge is pretty decent too. 100% on the internal rim width, those newer 25mm internal's make the tyre profile so much better!
Just converted my primarily road based gravel bike to Specialized Pathfinder 2bliss from tubes. Seems about every 100miles I was getting flats from road debris in my Schwalbe G1 All Ground with tubes. For those of us heavy dudes that ride mostly road, if the safe psi rating is 50-80psi, can I run the full 80psi tubeless?
Ok , I add 5psi to the value in the graph as I have tubes but it puts me 40psi wich is 10psi below what is recommended by manufacturer.. Generally all cycling sites and youtube videos present tire pressures that are cleatly below what is written on the tires.
Hi Peranders, It's a tricky one. A lot of riders will not follow the info on the tire walls as they often are over cautious with the numbers they state. That also means we/other sites/shops can't go recommending riders to go below/above the tire PSI limits. Basically the ride quality will be better, but we can't recommend you do that (or you'd do it at your own risk). Hope that helps!
To me those pressures are at least 20% too high! I would run those pressures on the road for better rolling but I would be shaken to death off road and slipping all over the place!
The worst thing I ever done was went to tubeless on my bikes, as if I don't use that bike for a few weeks, I've always got to top it up with air, I've gone back to tubes.
What pressure and tyre setup do you ride... do you agree with James' starting graph...let us know!

This chart is pretty spot-on!!

Wish id seen this years ago it would have saved me a lot of time! change mine for every ride now. makes a huge difference to how everything feels.
Glad it could help. Makes it ride like 2 different bikes!.
Great stuff, thanks James, this was a great explanation for what to do. I've recently moved to Schwalble Marathon Tour and it's like concrete, so eager to put some of your tips into use.
Great stuff Stewart! nothing worse than too many vibrations up though the saddle 😂 Hope they help

NICE! amazing how much difference a few PSI can make to the ride feel and grip! and you can get away with a lot on 27.5' 2.25 tyres! Enjoy!
The chart says 33 psi recommended for me but my tube 40mm says the minimum is 50 psi. What 2 do? 50 psi feels like ice skates
Really informative, thanks 😊

Does pressure impact puncture resistance?

Yes Gavin! Couldn't agree more, too many benefits not to. My booty needs as much extra comfort as possible. Chapeau!

It's a tricky game find what works best for you... glad you've found the sweet spot Richard 👍
@wiggle I run 60 psi in a 700 x 32c tubed.
Nice n firm! I'd imagine the smoother side of riding for you then👍
@@wiggle firm that’s soft ?
Ride 34mm & 31mm tires. Pressure from 28 psi to 36psi. 28 wet gravel/roots. 36 psi dry and smooth.
Nice! Running tubeless I can imagine, thanks for sharing 👍
I'm not brave enough to go tubeless, got to stay with the traditional tubes 😅😆 Also, where can I get myself one of them Wiggle mugs? 🤔😉
😀Took me ages to commit to the change, but it's been running perfect for me. Mugs were a limited run...but we could potentially make some more...
im 96kg
currently using continental 700x35c cyclocross king tires
70%road 30%uneven terrains.
what tire pressure should i have?
Hi, Good set of tyres. I'd say about 50-52 PSI should do the trick nicely. let us know how yo get on.
My experience.. lower than you'd think.
This weekend I ran my 43mm tyres at 28 and 24psi and it was fantastic, could just fly over the rough stuff without much concern.
Tannus with tubes
A good shout and definitely worth considering, we're making a video on a similar product soon 🤙
Lok for cyclocros 😅 tires
😅😅😅
The worst thing I ever done was went to tubeless on my bikes, as if I don't use that bike for a few weeks, I've always got to top it up with air, I've gone back to tubes.
you won't say that when you get a flatty 😉
