That's a good reference Lee. Thanks. I understand now that prior to the DOT mandate (which I thought was 1968) each manufacturer had their own dating methods. Since US Royal is out of business, I doubt I'll be able to decode the date.
Let's just suppose the 1207 indicates (1) the year, 1961, and 207 is the day of the year. That would make the manufacture date the 4th week of July, which just happens to be the week this car was built!
This tire also says low profile tubeless. 4 ply rating 2 ply.
