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
(possibly on the inside of the wheel), dis-
playing the DOT Code. 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 1622 represents that
the tire was produced in the 16th week
of 2022.
WARNING
Tire age
Replace tires within the recommended
time frame. Failure to replace tires as
recommended can result in sudden tire
failure, which could lead to a loss of con-
trol and an accident.
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.
