I presumed I would get a rough answer obviously there’s lots of variations. In motox which I raced for many yrs tyre pressures were very important and a few psi hear or there could make a big difference!
I was wanting a few ideas as to what people run.
But nevermind there’s to many trolls without anything else better to do (get bk on Facebook) thanks for the few decent answers I received.
Ah! Now given that bit of context your question doesn’t seem so daft. Seriously though, in mountain biking there are that many variables that mostly it comes down to your own preferences. As a rule though, 30 – 35 psi is about what most people use. Harder pressures mean the tyre doesn’t deform to the ground so much and so rolls faster but this is at the cost of grip.
FWIW I’m a great big heft rugby player type and I run 40 psi in the 2.1 tyres on my XC bike and about 32 in the 2.5s on my DH bike.
Ok, the serious answer is, it depends so much on the tyres, the bike, your style of riding and personal preference that its impossible for other people to tell you. And the idea of there being one recommended pressure for a particular trail centre is a bit daft.
Also, you picked Llandegla which for some reason attracts lots of controversy on here, so I think lots of people assumed you were trolling, and wrote silly replies.
Llandegla is my local, I run 21-23 front, 31-33 rear,2.2 Rubber Queens tubeless. It’s generally grippy, but I find too much air in the front, and on some corners it looses grip. If you are tubed, try 28f 30+rear. Have fun 🙂
