Re: Tire Pressure

24-25 psi should be just about right. Because these tires are the same type (bias-ply) as originally specified, you can go by the original recommendation. Bias ply tires have much stiffer sidewalls than radials do, so you can get proper performance with lower pressure.

When choosing pressures, the manufacturer is always trying to balance ride quality, tire wear, and safety. I wouldn't go any lower than 24 psi, but you could go up a bit to 30 psi or so (provided that's under the max, which it should be) and see how the handling and ride compare. An overinflated tire will not make full use of the contact patch, so going to the absolute max pressure is unwise.

Jist as an aside, I run radials on my car and have settled on 40 psi as the best radial tire pressure.
