Tire size
The code 3 indicates the tire size.
Tire type code
The code 4 may, as the manufacturer's
option, be used as a descriptive code for
identifying significant characteristics of
the tire.
Date of manufacture
The date of manufacture 5 identifies
the week and year of manufacture.
The first two figures identify the week,
starting with “01” to represent the first
full week of the calendar year. The sec-
ond two figures represent the year.
For example, "031" could represent the
3rd week of 1981 or 1991.
If the date of manufacture code indicat-
ed on the tire is less than 4 figures, do
not use it.
i
Prior to July 2000, tire manufactur-
ers were only required to have 1
number to represent the year in
which the tire was manufactured.
For example, "031" could represent
the 3rd week of 1981 or 1991.
