I was wondering if any one can tell me how to determine if a bias ply tire is an original or a reproduction? Here is the information that I have on them. They are a Goodyear F70-14; Tubeless; Polyester Cord; 4 Ply; Load Range B; V-1; DOT. Info. on the back side of the tires includes: DOT CYLDB3K71100; Speedway Wide Tread. Are there any key things to look for? I'm looking at picking these up from a someone and just wanted to know for sure what they are. I'm ok with them being reproductions. I'd just like to know either way. Thanks for any help you can provide.
