- Calvin and Truman continue their quest to understand tire pressure using the data from the Tyre Wiz, both on the trail and... under the forklift?

Calvin and Truman, great video! It would be interesting to see how products like CushCore effect the pressures in some of those situations as well.
Applying science to bikes is so awesome.
It would be really interesting to see the forklift test on a bmx wheel with a 100PSI tire.
Probably a lot less safe to stand in front of! ha
Great demonstration!
Maybe mix some TUMS with your sealant? Great video, thanks guys!
Great video Calvin and Truman!
Great videos guys. Helped me out a bunch. Thank You 👍
Thanks Calvin and your friend, very interesting
Great video absolutely love videos like this
Great vid guys
Awesome vid! ❤
@Park Tool is it possible to do a video on how to give your (road)bike a full service? The kind you expect from a a shop. Bottom Brackets, headsets, components, wheels.
30 in the rear, 25 PSI in the front 👌👌
Nice
It would be great to see a comparison to tire squeeze as at relates to tire width at a set pressure. Anything comparing a range of tire widths would great!
First of all, please excuse my poor english.
Excellent what's going on at 5:27. It can be used as a subject of a new clip.
You should test a correctly tensioned wheel in pseudo-real conditions. Measure the tension in the upper spokes versus the tension in the lower spokes. The difference is very important when we talk about correct spoke tension.If correct, the spokes should break when they are under the correct tension..
Keep your eyes peeled. There may be something coming very soon.
I knew it. Thx.👍
Nice use of a forklift
👍🏻
Cush Core. Nuff said.
Truman needs some park tool socks.
I see bicycle beadlocks in the future. Will be interesting to see what that looks like on a bicycle??
I was just thinking that the other day of what that might look like and how to accomplish it without adding too much rotational weight.
Truman that bike is dope, what is it? I've never ridden a 29er either, worth it?
Thanks! The bike is a Kona Honzo st. A steel hardtail that is aimed to be more "enduro" than others I have had. The 29" wheels are great for rolling over stuff. They are taking a bit to get used to though. But thus far I am happy with the bike. The bike will be used as a test bike to test components and stuff.
So what tubeless pressure should I run as a 240lb rider with 2.5" Front and 2.4" Rear 29er? The 300lbs of force is a bit concerning...
As a 265lb rider who has been losing weight from 300 in the past six or so months, I personally have had issues whenever my pressure dips below 25 psi with a front 2.5" DHF or under 30 psi on the rear with a 2.3" on my 27.5 in bike.
I rode a fat bike tire under 30 psi once and literally almost died when everything rolled out under me, but my helmet gave its life for mine.
@@i.e.sergio Thanks! Hmmm fat bike should have more tire volume and thus lower pressures especially tubeless. The sidewalls tend to be weaker though.
Haven't I seen this already, a couple of weeks ago? Was it published, pulled and then re-published?
You must be a Pinkbike viewer as well?
Ah, yes! I didn't remember that's where I saw it (and had always assumed PB were just embedding the TH-cam vid anyway, so hadn't appreciated they had an exclusive for a week or two).
How can I embody the fluctuation chart of air pressure on Garmin Connect Activity as shown in the video? Does it only need tyrewiz? or any others?
The Tyrewiz is the only one we know of that works with the Garmin, but search around and see if there is anyone else.
Honzo 👍
Im running Maxxis High Roller II, 27.5x2.4, EXO, Tubeless, 60 TPI, on the tire it says 40-60 PSI. All the videos I have seen say to do around 25-30 PSI. Do I go by what the tire says or what everyone else recommends?
I would go towards what people are suggesting. The label on the tire is max psi, not suggested psi.
@@parktool Thanks!!!
Having a 26" or a 29" does any difference to how much pressure should we put in?
Because the 29er has a larger volume of air, typical riding pressures are lower.
I haven't either of these gadgets, but shouldn't it possible to hack a ShockWiz (with valveadapter, and stuff like that) to a rim to get faster read speeds?
vote Pressure to low for the schockwiz
@@flemming_j_ Ahh okay... Didn't knew that
be nice if 30psi was included, and the weight of the rider in pounds and kg. so we can judge better in relation to our own pressure and weights
My rim got dents because of lo PSI. GOT A MAVIC XM 715. FOR FREE
My tires at 30 psi deflect or smoosh like yours at 16 psi
That depends on several factors, not only the tire material and structure, but quite importantly also on the overall tire volume. The fatter the tire, the lower pressure it allows.
I believe in having firm tyres - so I run mine at max or 50psi... I believe that comfort & traction should come from suspension & tyre compound... I believe that stressing(abusing)tyres - running low pressures - to achieve what I previously mentioned is wrong - I believe that riders should accept the imperfections of their riding conditions & should adapt to different situations instead of expecting(or forcing)their bike to behave the same in every situation... You don't 'have' to go fast in every situation & through all conditions - after all, we riders don't ride at the same speeds when riding uphill vs riding downhill don't we? (not even with E-bikes - well, not yet anyway) PS: Some of the most fun I've had whilst riding involved riding through river water which only allowed me to rock my crank back & forth(or else, soak my sneakers)... Being able to handle\adapt to different situations is more fun than being the same way throughout the situation\condition - that's why mountain biking is more fun that road cycling... =P
I believe i can fly ... I believe i can touch the sky ... I believe ...
there is only one response to your comment. And that is you...are... wrong! Drop your psi's to about 25psi front and 30psi rear and reap the benefits of your tyres actually doing what they were designed to do at the pressure they were designed to work at!
If you watched that video & still insist on running low pressures......You're Not Intelligent Enough To Assess Wrong From Right... I am not wrong(you're just making an excuse to call me wrong)... Abusing tyres by using too low a pressure to get grip is WRONG - REGARDLESS of weather an advantage is gained or not... There are other ways - & you don't 'have' to get maximum grip in every cirsumstance... Why don't you lower tyre pressure to ride on ice? The so called 'designed' to work at thing is more adapted to handle the abuse or running lower pressure... Tyres are NOT suspension & should NOT be run at low pressure to cushion your ride, & they should NOT be run at low pressure to get more traction...
Holy moly everybody calm down. The correct way to run your tires is whatever you like. If you want rock hard tires and it keeps you riding then thats correct for you. If somebody want to run low air pressure and they enjoy it, that is also correct. I personally run 22 psi front and 25 psi rear and that works for me in most situations. Ill wear the tred off long before the sidewalls wear out.
Marvin Connell Better get buisy then, EVERY Pro rider is doing it wrong 😂, So better get going prooving you are right, and both experts, and science (look up schwalbes Rolling test), are wrong😉
Hi sir hope you can notice me. I wish you can give me bike. To bike in trail to. 🙏
No bikes to give out but, Hello!
i stoped watching this series both time for he same reason: you count, and only, count in psi :/ maybe include BAR next time ;)
Hobbes TheTiger that’s because psi is the only relevant measurement
@@bobdixon3048 Maybe for u :D i dont have a clue what so or so much PSI feels like. And most european dont know that either. Im sure the video took much effort and it seems to be interesting af
Hobbes TheTiger I’m European and I enjoy using psi
@@bobdixon3048 whats ur point? :D
Everybody I know in finland, uses psi
