Correct tire air pressure

[Slonis]

hello everyone, we had our RAM rebuilt. We now have a 5 "RC undercarriage with air in it. And the tire size of 35 x 13.5 r 20 Radar Renegade RT +. can someone tell me what correct air pressure I have to drive so that I have a long tire life? Most of the time I ride alone and without a load.

I looked on their website and saw your tires, but not much info.
It'll be on the sidewall though.
