Wheel size designation
3. Checking tire life (TIN :Tire
Identification Number)
Wheels are also marked with impor-
tant specifications. The following
example of the wheel size designa-
tion explains how the letters and
numbers are interpreted.
Any tires, which are 6 years or older
from the manufacturing date (includ-
ing the spare tire), should be
replaced with a new one. The manu-
facturing date is written on a tire side
wall (possibly inside of a wheel) in
the DOT Code. The DOT Code is a
series of numbers on a tire, which
consist of numbers and English let-
ters. The manufacturing date is writ-
ten in the last four digits (characters)
of the DOT code.
Example wheel size designation:
8.0JX19
8.0
- Rim width in inches.
J - Rim contour designation.
- Rim diameter in inches.

DOT : XXXX XXXX OOOO
Tire speed ratings
The front part of the DOT are the
plant code, tire size and tread pat-
tern. The last four digits indicate the
manufacturing week and the manu-
facturing year.
The below chart lists up different
speed ratings for a tire of a passen-
ger vehicle. The speed rating is one
part of the tire size designation,
specified on the tire side wall. Each
symbol represents the maximum
driving speed of a tire.
For example:
DOT XXXX XXXX 1615 represents
that the tire was produced in the 16th
week of 2015.

Tire age
Tires degrade over time, even
when they are not driven.
Regardless of the remaining
tread, it is recommended to
replace tires every 6 years. Heat
under the hot weather or fre-
quent overloading may acceler-
ate the aging process. Failure to
follow this warning may result
in a sudden tire failure, leading
to a loss of control, accident,
serious injury or death.
130 mph (210 km/h)
149 mph (240 km/h)
Above 149 mph (240 km/h)
