Each tire is unique due to differences in the sidewalls and how the tire is made. My suggestion is to say what kind of tire you're running and see if anyone has any experience with those tires.

I think 12 psi is always a good start. Lower as needed.

Do you have onboard air?
If you don't, I would start around 20psi and work down from there till you find the PSI that works for you. All the answers you get are just peoples opinions on PSI that works for them, on the specific tires they have, on the specific trails they run. Its more a matter of opinion rather than fact.

Agreed. I just keep mine at 11psi, most of the time and if I get into a good enough spot Ill lower them to 7-9psi. However,I have the MTR Kevlars and they work great at that psi, even without beadlocks. That kevlar wall is awesome for low pressure.

What he said^^^ ... except IMO start at 18psi and work down. 9psi make be great for MTRs, 12psi may be great for BFGs, and even 15-16psi for others. But, you'd need to go to 5 or 6psi to get the same flex out of, say, a Michelin XZL.

It really is tire dependent-

I also run Kevlar MTRs and usually run trails at 10psi with no beadlocks.
