I suspect the gentlemen named Jan and Feb did not make my Firestone tires in the number 57 assembly line. Assuming I'm correct and that the tires on the bike are actually from 1957, I've done a search on the forum and found a good list suggestions to consider that include Avon, Dunlop, Mitas, Cheng Shin, and Heidenau. Thanks to everyone who added to those two recent threads.

How do tires this old look so good? Lack of UV rays?
