I'm trying to figure out the date of manufacture of a spare tire found in a '61 Impala. The tire reads:
7.50-14 safety 800. US Royal
Spare also says low profile tubeless. 1207-154 AA 686. 4 ply rating 2 ply. 20XD4
Any help would be appreciated. Although the size is correct, I have a hunch it's not the original spare. The wheel shows signs of being mounted and the tire has wear.
Thanks
Verne
