3. Checking tyre life
Any tyres that are over 6 years old,
based on the manufacturing date,
should 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.
DOT: XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tyre size and
tread pattern and the last four
numbers indicate week and year
manufactured.
For example:
DOT XXXX XXXX 1621 represents
that the tyre was produced in the
16th week of 2021.
