Tires: Goodyear Wrangler Silent Armor Date Code, Tire DOT Code

Question
Could you help me find out the manufacturing date of a set of four new  P265/70R17  113T tires?

All have after the DOT code  (MDT6  3PHR  3208)

Two have a small code 432R and two have a small code 431L
The small code is all by itself on the side of the tire, not part of the DOT CODE.

Thanks

Answer
Tom,

DOT codes are a 10 to 12 digit number located near the letters "DOT".  BTW the digits can be numbers or letters.

The first 2 digits are a code for the manufacturing plant.  

The next 2 digits are a code for the tire size.  

The next 3 or 4 digits are a code for the type of tire.  

The last 3 or 4 digits are the date code.  The format is week/week/year/year or week/week/year.  

Starting in the year 2000, the date coding used is 4 digits.  That means the highest number you should see for the year is 08.  Before 1999 the format was 3 digits.  1999 and 2000 are transition years, so you will find both 3 and 4 digits.


So the date of manufacture for your tire is the 32nd week of 2008
