Dave(dhgeyer) or anyone else, can you tell me/us, how to read the DOT codes on the tires to determine exactly when they are made. I have no idea what to look for. Thnak s in advance!

Somewhere on the side of the tire, you will see an inset with multiple strings of characters beginning with the letters DOT. The strings following DOT convey information concerning type of tire, where it was made, and when it was made.

The "when" information is contained in the last string (see below). This string consists of four numerical digits. The first two digits are the week of the year the tire was made, and the last two digits are the year. In the example shown above and below, the front tire on my BMW was made in the 42nd week of 2009.

One unlikely but possible exception: tires made before 2000 had a three digit date code, 2 for the week as above, but only one for the year. The decade was assumed. Any tire with a three digit date code is over 10 years old, and should be replaced ASAP no matter how it looks.
