For all things mountain biking. If it's pedal powered (or even pedal assisted), goes on two wheels, and belongs in the dirt, it's welcome here.

What isn't welcome: Hate speech, bigotry, assholery, road bikes...

'Religious debate' time! Check in with your tire pressure... (self.mtb)

I'm curious what other folks are doing pressure-wise.

I'm fairly lightweight (70kg, possibly after lunch? With back pack and water, who knows? I usually carry extra tools, etc...), and run 2.6" 27.5/650b tires.

Rear is around 20psi, but it's tubeless so I generally catch it once it's slipped down to 15 or 17 after a few weeks :). I've just realized I'm not even sure what the tire is, but it's a maxxis brand, so probably actually 2.4" wide compared to most other companies - not much clearance on my Intense Recluse

My front is usually about 18psi, on a specialized 2.6" somethingorother (pretty sure it's not a butcher)

If you don't hear your rim hitting the rocks in the trail, you are probably fine going down. If you go up a lot, you can try higher pressure and see how that feels as it will lower rolling resistance.

Then find a happy medium depending on how much uphill va downhill you usually ride.

I'm about 80kg +water and found 24psi to work best for me.
