- for tyres manufactured before 1 January 2000, codes are three-digit numbers. The first two digits represent the week of the year, the last digit represents the year itself. For example, the code 267 means the 26th week of 1997
- for tyres manufactured on or after 1 January 2000, codes are four-digit numbers. The first two digits represent the week of the year, the last two digits represent the year itself. For example, the code 2501 means the 25th week of 2001.
