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
Hope this gets you there;
