Maintenance
The DOT Code is a series of numbers
on a tire 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, tire size and
tread pattern and the last four
numbers indicate week and year
manufactured.
For example:
DOT XXXX XXXX 1619 represents
that the tire was produced in the
16th week of 2019.
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 accelerate
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.
4. Tire ply composition and
material
The number of layers or plies of
rubber-coated fabric in the tire.
Tire manufacturers also must
indicate the materials in the tire,
which include steel, nylon, polyester,
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 "Tire specification
and pressure label" on page 9-19.
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 factory 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.
