I've had Diamondbacks on my Cadillac for 10 years (after a belt separated on a Coker Classic in under 10k miles). The Packard has them and I've had them installed on a '56 Fleetwood and a '58 Coupe de Ville.
They're the best tires I've ever had on The Bismarck. These tires were made by Diamondback prior to their new Auburn design that has a sidewall around the tread that more closely resembles bias ply tires.
Of course, these are all wide white wall tires. If you want blackwalls, light truck tires from just about anywhere will be a whole lot cheaper.
