Could it be because of bias ply tires? I don't know when radials came out.

Read section 5 of the owners manual.For 78,they are refering to load range"B" radial tires.
But in no way would I run 20 PSI on the front for street.Not even 25.
32 PSI works good and allows for increases of 4-6 PSI for sustained driving which occurs when tires heat up.
Autocross is another matter. I used to start with 34 front,32 rear.
