How low is to low(psi)

[Captain Brainstorm]

I ride at 30+psi to avoid hitting something and feeling my rim, regarding feel(ignore psi) what do you feel for to no you are to low or to high?

Need details bro, how much you weigh? Inner width of your rims? Tire size/brand?

General rule of thumb, your PSI should be just enough that you're not burping sealant, rolling tires, or denting rims.

Like this:
Fat and 240lbs. Stan'sFlow EX 25.5mm, Ardents EXO/TR 2.4f/2.25r @ 18-20psi front, 20-22psi rear. No burping or folding and rim strikes are very rare.

I'm sure I can go lower - being conservative on the 27.5+ due to carbon rims

I'm at 9 in front 15 rear. 2.8's 200 lbs+ Never touched the rims so far. Any higher and I get bounced around. Maybe the gage is off???

it's too... not to...

grammar... it's the difference between knowing your shit and knowing you're shit.

But you let him go... on “no” and “know”

This is why I'm asking for feel and not psi

Lower it a few pounds at a time until it feels a bit vague or you start tagging the rim then up it a hair. It should feel planted and compliant on the rear and crisp but not chattery on the front. You'll know when you get it right, just keep messing with it on a section of trail that has varying terrain.

How often do I need to say IDC? 90% of my post are on mobile and I'm a lazy texter why don't old people get this?

Can't wait for this thread to start talking about elevation.

Damn bro. You running tubes? My understanding is tire size and weight matter. Dont let these 140lb people tell you 15psi. I'm heavy, so I run about 23 front 25 rear. I also do dumb noob shit like try to bunny hop and slam my rear wheel into roots and rocks, which is why I have a dented rim.

I'm running 29er 2.3 front and 2.2 rear. Smaller the tire, more pressure is needed...so I'm told.

@UtahJoe is not close to 140lbs i can tell you that much

I'm always tagging the shit out of my wheel

You're feeling the rim hit at 30psi? That's surprising.

 

[Juggernaut]

I rode my 27.5x3” at 12 front 15 rear
29”x 2.5 is 23 front 29x2.3 read 25psi

What’s with the real answer? Only snarky answers allowed........?

why don't old people get this?

umm... yeah... well...
i still have all my own teeth.

Ha. Just a jokingly vague reference to different factors. I assume skill is a factor as well. A better rider will be lighter on the bike.

I'm going to pick up another pressure gauge maybe mine is off but I know if I hit 33 I'm good

I'm more concerned about feel because I want to drop pressure because I am always spinning out of a climb

Ive been told I am too serious sometimes.
