Lowest pressure on nonbeadlock 285/75r16?

I used to have 33x12.50r15's on an 8" wide rim, non beadlock, and I dropped them at 15 psi to wheel with no issues.

I was wondering if anyone had any experience on these thinner tires (285/75r16). They are also on an 8" wide rim, but I was thinking that being thinner, maybe there's less of a "squeeze" to keep the bead seated. Anyone have a safe low psi idea, or should I still be good to drop them down to 15ish? Thankyou!
