The main advantage of higher pressures (especially for radials) is to lighten the steering at low speeds. It does work, and inflating radial tyres to say 42psi does not really cause any harm. Regardless of pressures, some radials are harder riding than traditional bias ply tyres so the ride will feel more uncomfortable - especially in a Packard.

I use Diamondback whitewalls (based on Toyo radials) on my 1941 120 Club Coupe. I run these at about 38psi, in deference to the bonded white sidewalls. That also reduces the steering effort at parking speeds, which is a nice benefit. The ride does not feel noticeably worse, maybe because many road surfaces today are better than in the day....
