U.S. DOT Tire Identification Number (TIN)
and tire manufacture date
This is the tire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federal standards . The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example, the numbers 4513 mean the tire
was produced in the 45nd week of 2013. The
other numbers are marketing codes that may
or may not be used by the tire manufacturer .
This information is used to contact consumers
if a tire defect requires a recall.

WARNING
=
-
- Using incorrect or unmatched tires and/
or wheels or improper tire and wheel
combinations can lead to loss of control
collision and serious personal injur y.
'
- Always use tires, rims and whee l bolts
that meet the specifications of original
factory-installed tires or other combina-
tions that have been specifically ap-
proved by the vehicle manufacturer.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of the ir "previous histo-

aged even though the damage cannot be
seen that can lead to sudden tire fa il ure
and loss of vehicle control.
- All four whee ls must be fitted with radial
tires of the same type, size (rolling cir-
cumference) and the same tread pattern .
