Maintenance
3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over 6 years old, based
on the manufacturing date, (including the
spare tire) 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 num-
bers on a tire consisting of numbers and
English letters.The manufacturing date is
designated 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 numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1517 represents that
the tire was produced in the 15th week of
2017.
4. Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire. Tire manufactur-
ers also must indicate the materials in
the tire, which include steel, nylon, poly-
ester, and others. The letter "R" means
radial ply construction; the letter "D"
means diagonal or bias ply construction;
and the letter "B" means belted-bias ply
construction.
5. Maximum permissible inflation
pressure
This number is the greatest amount of air
pressure that should be put in the tire. Do
not exceed the maximum permissible
inflation pressure. Refer to the Tire and
Loading Information label for recom-
mended inflation pressure.
6. Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried by the tire. When replacing the tires
on the vehicle, always use a tire that has
the same load rating as the factory
installed tire.
WARNING - Tire age
Tires degrade over time, even when
they are not being used.
Regardless of the remaining tread,
we recommend that tires be
replaced after approximately six (6)
years of normal service. Heat
caused by hot climates or frequent
high loading conditions can accel-
erate the aging process. Failure to
follow this warning can result in
sudden tire failure, which could
lead to a loss of control and an
accident involving serious injury or
death.
