Re: date on these tires
We've had a few threads about this previously. At the end of the DOT string of letters and numbers, if made after beginning of 2000 there will be 4 numbers. First 2 are the week, second 2 are the year. Pre 2000 have 3 numbers, first 2 are week last 1 is year i.e. 168 is 16th week of 1998. Sometimes there will be a triangle next to the number to distinguish 1990's from 1980's, but not always.
In the area of the DOT number there will be a brand with a string of numbers and letters for each time the casing was re-treaded, if any.
