Recommended tire air presssure for modern radial tires and 1947 Packard Custom Super Clipper

Post by merletanner » Mon Mar 04, 2019 9:20 am

Good morning,
Can someone give me some recommendations on the best tire air pressure to run on a modern radial tire 700R15-3.75 on my 1947 Packard Custom Super Clipper?
thanks,
Merle

Good question and be interesting to see what the consensus pressure will be. For what it's worth, while there is no definite recommendation for a specific size there is a recommended starting point in the current Diamondback catalog. For my two cents, with a radial I doubt I would want to be much below that number.

Thanks Howard.
I called Diamonback. The customer service person recommended 44 psi for my size tire 700R15-3.75

Interesting. I was going to say 40psi. So we are all in pretty close agreement. 44 psi is probably even better on a heavy car like that.
