This is a 4.40-4.50 x 21 Firestone Deluxe Champion 4 ply tire. Not sure of production date or what it came off of but MG , Jag etc. comes to mind. I have piles of old tires like this that have been sitting in storage in shops for decades and decades.This tire would be great for a spare, putting on your car as a roller or short distance driver. While it is ankle deep in tread,don't think I would go out on the Interstate with it. Though it is Gum Dipped.
