Tyre age
- Tyres should not be older than 6 years. Not even the spare wheel.
NOTE:
- The age of the tyre can be determined via the manufacturer's code, which is listed behind the DOT code on the tyre sidewall. The date of manufacture (the last three digits) is located at the end of the code (up to 1999, the last 3 digits or as of 2000, the last 4 digits).
- For the years 1990 to 1999, the 3-digit code is sometimes supplemented by a triangle suffix.

Example 4-digit identification
