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)
