Good question.
35 PSI.
For the record, I ran 37-39 in my 295/35/24. If I had 22s I would run 36 or 37.

Look at this chart for example. The largest 24 inch size has a smaller load rating than the largest 20 inch size, both at 50 PSI.
This means the 24" wheel needs a higher pressure to achieve what the 20" tire achieves at a lower pressure.
This chart also means that, on the same vehicle, the 24 inch tire needs to be pumped more than the 20 inch tire to have a normal tread-ground contact width, while the 20 can be pumped less.
Kapish?
