i wud sa n e were between 35 and 50
Sorry, just wanted to point out that typing in "AOL'ese" makes it harder for us to read and therefore, harder to help you. Taking an extra second to spell words out helps everyone.
35-50 psi is typically a good range. It depends mostly on the type of riding. If you ride mostly roads, run it closer to 50 psi. If you're riding in soft or sandy dirt, you'll want the lower pressures to give you better traction.

It depends on how much you weigh, and what type of riding you do.

I like a hard ride so I put 50psi in the rear and 60psi in the front using 26x2.0 tyres. I figure the front tyre can have more air as the suspension takes out the harshness. I ride mainly on fire tracks which aren't that bumpy. The type of terrain can be the deciding factor. But it's also personal preference.

In my mountain bike, I have around 50 PSI, and use it for jumping, freeride, light dh etc, most things really
Trials bike anything between about 15 and 30 PSI, depending on terrain/moves etc
BMX about 80 or 90
Road bikes 110
For my other bikes, and generally at work, I pump tyres up to around 40 (depending on the particular bike and pressure guidelines on the tyre sidewall)
50 PSI sounds about right to be honest, but check your tyre first.

Throw the stick!!!!
It depends on what tires you are running and what terrain you are riding. Tubes or tubeless?
On mine I generally run between 36 - 40 in the front and 38 - 42 in the rear. This is with continental explorer / escape tires using Stan's no tubes. This is for rocky, rooty singletrack where traction is very important.

Uh....no - it usually gives you the acceptable range of pressure (ie. 35PSI - 60PSI.)

I run 38 on my XC bike and singlespeed, 32 on my freeride bike. Low pressure = better ride. Unless you are using really small tires, or a lot heavier than my 155lbs, I wouldn't worry about pinch flats. I have NEVER had one.

40 for dirt and road? Sounds low to me. If your using knobbies on road i would look at the 60's. If you wnat the most efficient machine use slicks for road .

To each their own, and terrain and tire choice has everything to do with it. But my impression is many I ride with pump their tires up too high.
On my 26" bike (2.4" Mutanoraptor/2.1" Traction Pro) I ride 30 psi front and 40 psi rear.
On my 29" bike (2.1" Nanoraptors) I ride 28 psi front and 38 psi rear.
FWIW, I weight 200 pounds.
This is a nice balance where I don't get killed on rocks but can maintain traction up most climbs.
It's important not to go too low or you'll be in danger of snake bites and bent rims.
An easy way to adjust it to start with 45 or 50 psi, but leave your valve caps of and your stems open. Every mile or so reach down a release a quick pfffttt of air. Pay attention to how the rear hooks up on climbs, and how the front tracks on the downhills. You'll know when you go to low because the bike will feel squishy and have some side-to-side "flex". Plug a tire guage in and read what pressures you ended up at. Continue to play with your pressures in small increments. Higher for tacky and smooth rolling trails. Lower for loose, steep and dry.

WOW!!! must feel like ya'll are riding on steel tires.
In sandy conditions I run between 18 and 22 psi, hard packed, and rocks I run 25 to 30 depending how big the drops are (2.5 NBX tires). As for snake bites, I have had 3 in 10yrs of riding/racing and I use tubes and I weigh in at 265lbs.
What it comes down to is how the bike feels to you. I would suggest trying different psi and decide which feels wright for your style/type of riding. Higher psi will give you less rolling resistance but less traction, lower psi will give better traction but higher rolling resistance.
