3. Checking tyre life (TIN: Tyre
Identification Number)
Any tyres that are over six years old,
based on the manufacturing date,
(including the spare tyre) must be
replaced by new ones. You can find the
manufacturing date on the tyre sidewall
(possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tyre consisting
of numbers and English letters. The
manufacturing date is designated by the
last four digits (characters) of the DOT
code.
