The Stovebolt Site Forums The Shop Area General Truck Talk Tire Size Confusion: 1955 Chevy 2nd Series 3600

I have found those on-line and I'd rather buy those. I most likely will thanks to the stimulus check. I was hoping there might be a used, cheaper Radial option on facebook. Now, can I get away with a narrower tire on that rim? Perhaps a 6.70-15? Maybe a 6.50-15?
