Can anyone tell me with certainty what year wide rear sleek tires became available?

Here is Hollywood hotrods owner Troy's coupe and that's what he's running in the rear. I see cocker has some that are dot approved. Mmmmmm...



Could I use his car in my flash back 1955 movie scene or would it not be period correct because of these tires? Could they have been on a 1955 hotrod? Or impossible?

NOW LET'S NOT GET INTO A 120 POSTS DISCUSSION ABOUT SLEEKS VERSES RADIALS PLEASE. Just answer the gosh darn question which is - just to be sure you are listening and paying attention:

WHAT YEAR DID THOSE TIRES START BEING USED ON HOTRODS? Thank you!

OK, off to sleep now... ZZZZZZZZZzzzzzzzzzzz me so tired....
