I find this at odds with what I see on my cars. The sticker on the inside of the glove box door on my '51 specifies the tire pressure to be 26 to 28 psi (I will get the precise figures when I go to my shop). This car obviously came with bias plies when new. Every car I have seen running radials as OEM has a sticker specifying something in the low thirties.
Just an observation.
