What I don't get - how did they know if the steel wheel has to be black or body color if the written down R, X or W refers to the tire? If the letter refers to the wheel, like X for black steel wheel - how did they know which tire to use?
I have and old friend that mounted tires and wheels on the line ,it was his first job. He said the tires were mounted upstaires using a broadcast sheet for color size and type and dropped down to his location to put on the car. He also said if they lost count or what ever after a good lunch in the parking lot you mounted what ever came down there was no stopping the line for mistakes, it happened all the time. The quality people at the end of the line would correct mistakes which would account fot date codes not matching perfectly. I know that doesn't explain the trunk lid markings or when the spare went in but I'm about due to call him and see if he's still kickin maybe I can get an answer.
