Just playing with mine here…..

First time tubeless that is !

I’m 12 stone 4 in the flesh, so about 13 stone in riding gear.

On my 26 Soul with tubes and Purgatorys I normally have about 33 front, 35 rear.

Tubeless setup on 650b Anthem with nobby nics. I’m thinking 25 front and about 28 rear ?

depends on the riding. if it’s my normal rural roads and tracks usually about 30 front n 35 rear but if I’m going out to play on proper technical tracks or trail centres I drop it down to 15-20 front and 20-25 rear. Tubeless of course. I run purgs front n back.

I’m 16 stone and just set up a 29er purgatory front and ground rear, at 25psi. They felt pretty good.
Generally run about 30-35 with tubes.

Butcher front 22, Purgatory rear 22 on all the bikes. Tubeless

There’s an app for that…

Same as Tracey about 20-22 both front and back

To feel (all pumps read different) not too squidgy or rolling on the rim, not trashing sidewalls soft or pinching to the rim. Softer than tubes

About 25 rear and 22 front.
Running 1000g, 650b, WTB tyres, tubeless with huck norris inserts.
Works well for me at 12 1/2 stone.
I did blow a little sealant out of the front on a particularly hard landing recently …..might have to go up a wee bit.

90kg on a 650b hardtail, Vee tyres Fluid & Float. Mainly ride South Downs/Lordswood so chalky & rooty. 30psi on my pump feels too hard so I go about 25, which seems fine if not occasionally too soft on the rear.

I run about 18 front and 22 rear when on local soft stuff but I find that squirmed way too much at trail centres with the fast berms and rollers so they go up to mid 25s for that.

cheers folks, seems like I am in the right ballpark..

15F & 18R in 27.5×3 TL
22 & 25 in 27.5×2.4 TL
23 & 26 in 27.5×2.3 TL
8 & 8 in 26×4.6 tubes

That’s what I set them to when I pump them up, which is by no means every ride, they’re usually way less than that when I think, ‘oooh, that feels a bit squidgy….’

19F and 24R, but then I wouldn’t use tyres as fagpaperesque as Nics!

My 78kg-81kg weight equates to me running 29×2.25 tyres at 21-22psi F / 23-24psi R tubeless (Rocket Ron Evo Snakeskin / Racing Ralph Evo Snakeskin).

83kg, 650b rigid, tubes… 😳 Attached pump at the weekend to drop a few psi after a recent ride, now sitting at:

17psi front 3.0 Purgatory
23psi rear 2.35 Nic

I ride local Chilterns bridleways, so basically fields & thick woodland clag.

mid-30s in 29er tubeless S-Works Ground Controls. I’m 16 stone butt nekkid, so any lower pressure I can feel the rims hitting rocks. And given they’re rather pricey carbon ones, I’d rather they didn’t.

I’m about 13 and a half stone without kit and I run mine tubeless, front minion 27 and rear aggressor 30. I hate a squidgy feeling bike so run my suspension pretty firm too though

anything above 60a and Schwalbe’s pace star compound just not grippy enough when it gets damp because it is just too hard…

ok i know I am late with this but its funny in my head.

run 20 front (sometimes 18 in winter) on a 27.5 hans dampf trailstar

run between 30 and 25 on the rear (26″) hans damph or new nobby nic.

Agree with the above but switched to a new nobby trailstar and Jesus Christ its draggy

Ideal, have gone with 25 front, 28 rear on FS with 650b Nobby Nics and it rides great, thanks.

Just setup the 26 Soul last night, with Purgs, on Mavic 719’s at the same for now but suspect they may be a bit squirmy…

85Kg and run with 25F, 28R with Bonty XR4/XR3. Rolls well and still has lots of grip.

75kg, SuperGravity Magic Mary out front, SG HansDampf out back

22psi in the rear, pretty much all the time

Front as follows:

1) wet rooty or slippy rides, down to 18psi
2) Normal stuff, 20psi
3) DH stuff, up to 22psi to avoid pinches etc and stiffen the carcass under high loads

According to the guage on my pump

9 psi front
15 rear

Bonty XR4 2.35 tyres on 650b 26mm internal rims, with tubes.

So in other words, no idea.

26 x 2.35 & 650b x 2.35 hardtail and FS respectively. Was recently as low as 16psi rear and 14 front. Now gone a little higher – 20 rear and 18 front.

The Blackburn track pump tells me about 17/25, the Bontrager roughly 25/33.

I’ve given up on pump gauges, tbh.
🙂

Soft as I can really. 6psi both ends on the fatbike, usually 20-25 somewhere on the normal bikes (with reasonably sidewally 2.3-2.5 tyres). I’m 10 stone though so with dualplies I can almost get away with no air at all 😆

With plus tyres I ran into orrible cornering blobbiness but it’s not a problem I’ve ever had with normal tyres, so I just want to be as low as I can without flatting/destroying rims.

11f/12r for b+. Around 18 on my rocket. I don’t mind a little rear tyre squirm. All tubeless. Measured with digital pressure gauge.

Running with tubes
I’m 11st, wet through

21 front (Hans Dampf 2.35)
A little more on the rear (NN 2.25)

Used an old pair of spesh butcher/purg on the 29er this weekend.

I used to think they were alright, bloody awful grip on wet rock.

The bin beckons.

16 front, 20 rear using a Topeak digital gauge.
Nobby Nic 2.25 front, Rocket Ron rear on a 29er xc bike

15st riding weight:
WTB Convict 2.5″ light/high grip 22psi front
WTB Vigilamte 2.3″ tough/fast 25psi rear

Maxxis DHR2 ST dual ply 2.4″ 20psi front
Maxxis DHR2 60a dual ply 2.4″ 24psi rear

(Joe blow & Schwalbe gauge read the same)

you used to sing their praises, how come they are so shite now ?

Purg’s never been very good tbh. Butcher Control is a great tread but fairly hard rubber so not ideal for wet greasy rock, only soft rubber really copes with that…

interesting – I went to Purgs front and rear on my Soul a few years back and haven’t thought too much about them since. I did pop a butcher of the front for a while last summer – great grip but a bit draggy on my local stuff. Not sure how squirmy the Purgs will be tubeless on unfashionably narrow Mavic 719’s ? The were fine with tubes at 32/35…

This weeked at the Golfie on the Reign was 15psi front, 17psi rear (Topeak Pressure Gauge)

As the trails dry out, will go up in pressure, 18 front, 20-22 rear. 29er runs same pressures.

I keep trying to run 20+ to increase my confidence that 2.3x29er tyres won’t fold in the corners

But as soon as I see anything steep and muddy I tend to drop a lot of pressure. It’s hard to refuse the feeling of security it gives and I won’t be cornering hard in those conditions anyway.

Sometimes when I measure it later I find out I’ve been running around 10 each end! With tubes as well, and plenty of sharp limestone bits on the local trails.
