IPS 121/122/123 tire pressure

On my IPS 122 I  have a Chao Yang tire that doesn't specify the what pressure it should inflate to. There is a marking which says Max load 70kg at 250kPa (154lbs at 36psi). So I have been riding at 36psi but I'm wondering if it should be something else.  Does anybody know?

My IPS 121+ tire is a Chao Yang 16 x 2.125 / 54-305 and it shows tire pressure 35-45 psi.

Then it's the same as Firewheel (size & manufacturer). I've kept mine around 3.5-4 bars (around 51-58 psi), no problems, but I'm lighter weight.

I have 2 IPS 121s. Both have the 16 x 2.125  tire size. One tire says 44 psi, one says 36 psi. I keep both of them around 50-52 psi with no problems. I think the wheel feels much livelier at this pressure. You get much less cushioning at this pressure though. You feel every bump. However, when I go back to the lower pressure, I find that I definitely prefer the handling at the higher pressure.
