Just had a quick ride out on my new set up Tubeless rims with 2bliss specialized tubeless ready tyres.
Got quite a bit of pressure in them and when i hit something or corner hard you can see the sidewalls crinkle up (if that makes sense)? Can't say i ever noticed them do this with tubes in then again i did not take much notice is it normal? I seem to be running more pressure now as at lower pressure there seems to be more movement in the tyre but maybe i am imagining it?
Got a day out planned Thursday and i am probably thinking more about having no tubes than i should be lol
I've always ridden 30PSI. Put that into my tubless tyres and they were far too hard!
Currently running around 25
Start at 30psi and reduce by 1psi each ride until you aren't in control. Then add a couple back in.
And you can have differing pressures in front/back.
About 22-25psi works for me.
Maybe I'm running way too much i reckon i have 35+ in there and they seem to flex like mad, Not got a tyre gauge at moment but lidl might come to rescue,

Without a gauge, no point guess.
But either add some or take out and go for a ride.
I've just set up some specialised 2bliss ready tyres but yet to ride them.
I have noticed they have very thin sidewalls so hope after reading this the tyre doesn't roll off the rim on high speed cornering.
And you can have differing pressures in front/back.
Assuming tyres are the same size, it makes sense to run a bit more in the back tyre. When you're sat on the bike, quite a bit more weight is centred over the rear wheel than the front. Totally subjectively as it suits me and my riding style, I tend to run about 35psi in the rear and about 32psi in the front on a 2.2" UST setup. I'll drop a bit out for a bit more traction if needed.
I run 23psi front, 25 rear, or thereabouts.
Your tyre should be deforming around stuff, that's what gives you better traction and feel, and without tubes you get no snakebite punctures.
Bontrager tyres appear to have very thin sidewalls, but I've done a fair few miles on them in the past with no problems. Don't expect Spesh to be any different 🙂
b r has it spot on, start at 30, and reduce gradually until they squirm add a bit back in.
27.1828 psi
25psi front and rear running LUST High Rollers.
7 psi front, 8 psi rear.
Well, its a fatbike! 😀
I run exactly the same as I did with tubes about 32-34ish Ardent EXO. Feels about right.
when i hit something or corner hard you can see the sidewalls crinkle up (if that makes sense)?
It does but I would suggest looking at where you are going...
Or psi = (your riding weight in stones X 2) and add 2 for the rear tyre and subtract 1 for the front.
So for me that would be 11 X 2 = 22, so 24 psi rear and 21 front. It actually seems a pretty good starting point anyway and is pretty much what I use.

+1 for that. 31 rear, 28 front seems to work great for me on normal stuff (14.5 st)
