DOT Number - Jon - 04-27-2005 14:45
Here is what the internet says about DOT Numbers. (DOT B38T ABV X577)
How do I know how old my tires are?
Each tire has a required Department of Transportation number imprinted
on at least one of its sidewalls. That number begins with the
letters "DOT" and may contain up to 12 additional numbers and letters.
The first and last digits are the most important for the tire owner.
The first 2 letters/numbers identify the manufacturer of the tires.
Prior to the year 2000, the last 3 digits of a DOT number represented
the week (2 digits) and the year (1 digit) of production.
For example, if the last three digits are 439, the tire was produced in
the 43rd week of 1999. Tires produced after January 1, 2000 have a 4-
digit date code at the end of the DOT number. The first 2 digits
represent the week of production and the last 2 digits represent the
last 2 digits of the year of production. So, 3500 as the last 4 numbers
indicates that the tire was produced in the 35th week of the year 2000.
Now all I can figure out is that my tires were manufacture in 1987 on
the 57 week. Is this right and if so boy these tires really haft to go!

Well with all that going on around here I misread those DOT Numbers on
my old tires and the real number is 357 and that makes more sence. But
that also means these tires are almost 8 years old and time to replace.
Thanks for all the help with this problem and now to find some extra
cash. Jon
