Got a 2.3 Kenda Blue Groove on the front and a Nevegal 2.1 on the back, I weigh around 13 1/2 St and ride a Kinesis XC>130. What psi would you recommend?
depends what riding your doing, if you wanna ride fast XC then 60 psi is a good start.
if you want more grip slightly less.
experiment, ride your local route from start to finish at different pressures and compare.
60psi is far to high for a mountain bike, start of at 35 and go up or down as required.
Ride to harsh lower the pressure
Tyres to skwirmy the up the pressure
Depends what kind of surface you're riding really and how bouncy/grippy you like your ride to be.
I'm sure I heard chris boardman recommend 28psi on the olympic coverage the mtn bike race!
Squishy....but not Squooshy.Like a slightly over ripe melon or firm kiwi fruit.
90kg - rubber queen BC- 35psi
Once was told:
no harder than the ground
Still wonder quite what that means, but always comes to mind when I'm pumping away (!) But it does make me keep the conditions in mind..
For tubeless starting point; Stan's say to take your all up weight in lbs / 7 . Take off 1 for front and add two for back as start point, the go up or down in 2psi increments. I found this still worked for 2.2ish tubed tyres if I added 2 psi..
Or just put 25psi in keep adding 2psi till it feels right cornering and you don't hear or fell the rims on square edges 🙂
Have fun
Check your gauge before you use it on a tyre...I have several and none are dead-on.
Worst reads 20psi with a real 32psi in the tyre.

I personally use 30 psi as the starting point. When I started, 40 psi was my starting point, but nowadays I find 40 psi + just means I'm skipping from rock to rock.
Higher than 40 psi is pretty much reserved for roads I'd have thought, but everyone is different.
Thanks! Was running nearly 60 psi, will make some alterations!
I'm sure I heard chris boardman recommend 28psi on the olympic coverage the mtn bike race!
I thought I heard him say 5 bar during the ladies race yesterday....
Uninformed??
