Checking a tire life
If any tires that are over 6 years based on the
manufacturing date, tire strength and performance
decline with age naturally (even if the tires are not
used like a spare tire).Therefore, the tires should be
replaced by new ones including the spare tire. You
can find the manufacturing date on the tire sidewall
(possibly only on the inside of the wheel), which has
DOT marking. DOT is serial numbers on tires,
which consist of a combination of numbers and
English letters. You can check the manufacturing
date to the last four position of the DOT.
WARNING - Tire Temperature
The temperature grade for the tire on your
vehicle is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause heat build-up and
possible sudden tire failure. This can
cause loss of vehicle control and serious
injury or death.
DOT : XXXX XXXX OOOO
The front part of the DOT means a plant code
number, tire size and tread pattern and the last four
numbers indicate week and year manufactured.
For example ;
DOT XXXX XXXX 1602 represents that the tire
was produced in the 16th week of 2002.
WARNING
A tire more than 6 years old may cause
separation of the cord layers inside the tire
leading to loss of vehicle or a serious
injury. Therefore, make sure to check the
manufacturing date and replace the old tire
in 6 years after the tire manufacturing date.
