Tire Pressure for upsized tires/wheels

So I upgraded the 66 DDArt from 13in, to 14in. Went upto 205/75. My 13's were 185/70.

This is my question, the suggested tire pressure from the manual says 24psi? That just seems to soft.

Now that I have the 14's, and they are a little wider/taller, does that mean I need to increase PSI or just keep it at 24?
