That’s what I am running on a 64 El Camino it works out pretty good. I like black walls anyway so I don’t worry about it, then you can pick the tire you want. But I’m not running a show car, I like good performance in a tire and pick it based on that and what I want to spend.
I googled 215 60 15 white wall tire and see a company called Calli under callietw.com and they have one in 3 white wall widths. I have no idea of tire performance. $131. Probably others too, keep looking

Very poor and getting worse tire selection in 14″. OK diameter in that size. Good selection in 15″ and even better in 16″ as they are still a modern wheel size. Lots of Hondas and Toyotas running around on 205 15s and 16s. No one uses 14″s anymore so few modern tires are made in it.Seems like white wall is your main criteria so you need to compromise between performance and cosmetics. Good luck in your search.
