Hello, just changed four Michelin PRIMACY3ST tires, and found that the tire sidewall code is OC49 04EX. Why are there only these eight codes?

For example: DOT: Ministry of Communications.

Manufacturer and factory code

P2/ France: tire size code.

For example: optional code of the manufacturer?

1 108: production date:No.1/week, 2008? (Made in the 1990s? ◥ Representative)

As in the example above, the dot is followed by eight numbers.

Michelin tires sold regularly have certificates attached to the label paper of the tires. There is a silver coating on the certificate. You can scrape off the coating according to the instructions and find the number 16.
