What tire air pressure to run on sand?

I'm planing on taking my 2015 SR5 out on the beach this summer. It's been a few years since I've been on the sand what tire pressure should I air my stock tires down to? Thanks in advance.

 

i have best success with 10PSI on the front, 15PSI on the rear.

If thats too low for your comfort level, try 15 all around and if you get stuck air down to 10.

 

10 might be too low for stock tires. Then again even on my load C duracraps, lowest I went was 15.

 

I was thinking 15psi but like I said it's been a while.
