So, where does one get new tires for their 28 Packard these days? (Mine is a 443) I don’t know just how old mine are but I wouldn’t be surprised if they’ve been on there since the car was restored in the late 80s.

..... sorry for intervening here... but since it's on topic......
Does anyone know the specific tire pressure for the 33x5 Goodrich Silvertown Cord? My Packard service manual generally says 50 psi for front tires and 55 psi for rear tires. Does this apply to all tires that were on the market at the time?

I'd imagine Coker or Universal Tire would have the correct style tires. I know Coker has an application menu on their website when you tell it what car you have and they let you know what tires "should" fit. It came back with the correct size on my 37.

Concerning tire pressure:
Owner's manual or shop manual pressures for your specific year and model and body style should apply to any brand tire of the same construction and size as original equipment. I tire pressure specs usually assume a full passenger load, with tire pressure checked cold. Later models with "balloon" tires on drop center rims often had very low tire pressure recommendations, such as 22 PSI for 1937 120 coupes. Adding 10% to that is probably a good idea. Earlier cars with "clincher' type tires and rims had higher pressures specified, usually 50 PSI or more, and it is not safe to reduce the recommended pressure by any significant amount with clincher type tires and rims.
