Tire Pressure

Owners manual and service update suggests pressure at 25 and 24, respectively, for correct size (760x15) bias plys. Others suggest to use the max cold psi on the sidewall.

Our Packard has 820x15 (L78) bias plys - slightly oversized - and is used occasionally for a school, town or church run.

I am accustomed to radials, a different beast altogether, I know; And so I lean toward much higher pressures.

Should I really keep these bias plys at 24 psi? What say y'all?
