Default Correct pressure for 20" tires

I recently switched from factory 18" wheels to 20" with Toyo A/T's (LT305/55/R20) tires with a 2" leveling kit. It handles fairly well but still has a little hop to it. I did the chalk test (at about 35 psi) and I'm showing more wear in the center. How much would you think I need to take the pressure down?

There are so many variables, but I'd think for a 33.....around 32psi cold give or take??

I ran 35s in the past in the 30psi range cold. Run 37s in the 27-28 cold.

Well, the one thing I'd note that I didn't orginally, I have 17" wheels. Still, it's a hard question to answer as weight, geographic location, specific tire wall strength....there are just a lot of variables. But, looked like you're chaulk test was showing the center of the tire still a little high, so I'd let some more air out.

I'm letting them cool down some now then I'll check the pressure again.
