3. Checking tire life
Any tires 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 tire sidewall (possibly on
the inside of the wheel), displaying
the DOT code. The DOT code is a
series of numbers on a tire consist-
ing of numbers and English letters.
The manufacturing date is desig-
nated by the last four digits (charac-
ters) of the DOT code.
DOT: XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1622 represents
that the tire was produced in the
16th week of 2022.
CAUTION
Tire age
Replace tires within the recom-
mended time frame. Failure to
replace tires as recommended can
result in sudden tire failure, which
could lead to a loss of control and an
accident.
