Welcome to the forum.

Best answer to give is, do the chalk test. There are so many different variables to give a specific PSI. You can Youtube chalk test and see what I'm referring too. Also, if you want answers within 20 minutes, usually forums aren't the best place for that.

I'm guessing such a small tire on such a massive rim, you're running a lowered JKUS? We don't actually have enough info to answer that question.

But here is how you can answer it. Look up your manufacturer's website. For instance - most lowriders like Nitto tires so I've looked them up for you in your tire size:

33x12.50R20LT E 114Q 200680 21.0 32.95 12.80 8.5-(10.0)-11.0 2600 @ 65 71.03
35x12.50R20LT E 121Q 200570 21.0 35.04 13.00 8.5-(10.0)-11.0 3195 @ 65 77.45
37x13.50R20LT E 127Q 200540 21.0 37.05 14.13 8.5-(11.0)-11.0 3860 @ 65 87.66
38x15.50R20LT D 125Q 200510 21.0 37.72 16.30 11.0-(12.0)-14.0 3640 @ 50 100.70
40x15.50R20LT D 130Q 200720 21.0 39.72 15.91 11.0-(12.0)-13.0 4190 @ 50 108.23

We can see that for your size tire the max tire pressure is 65lbs. Don't exceed that. But for comfort's sake I'd not exceed 40lbs on road. And I wouldn't offroad with low profile tires at all. You're just asking for trouble.

Here's the manufacturer's website where I got the info:
