Maintenance
3. Checking tire life (TIN: Tire
Identification Number)
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,
displaying the DOT Code. The manufac-
turing 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, tire size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example, DOT XXXX XXXX 1621 rep-
resents that the tire was produced in the
16th week of 2021.
WARNING
Tires degrade over time, even when they
are not being used. Regardless of the
remaining tread, we recommend that
tires be replaced after approximately 6
years of normal service. Heat caused by
hot climates or frequent high loading
conditions can accelerate the aging pro-
cess. 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.

4. Tire ply composition and mate-
rial
The number of layers or plies of rubber-
coated fabric in the tire. Tire manufac-
turers 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 per-
missible inflation pressure. Refer to "Tire
specification and pressure label" on
page 9-5.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tire. When replacing
the tires on the vehicle, always use a tire
that has the same load rating as the fac-
tory installed tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
