Is my 21 year old car still on its original tyres?
Discussion
Here's one for the tyre geeks:
My car left the factory in August 1991 (during week 34).
I am trying to ascertain how old its Goodyear Eagle tyres are.
I understand that you can work this out from the last figures of the DOT code.
The fronts (235/45 ZR17) read: DOT NJA5 2JK2 131
The rears (265/40 ZR17) read: DOT NJT3 2JP2 410
Does this means that the fronts were manufactured in week 13 of 1991 and the rears in week 41 of 1990? If so that's pretty amazing/scary!

that's my understanding. Pre 2000 it's a 3 digit code (wwy).Wiki said:
In the United States, the DOT Code is an alphanumeric character sequence molded into the sidewall of the tire for purposes of tire identification. The DOT Code is mandated by the U.S. Department of Transportation. The DOT Code is useful in identifying tires in a product recall.
The DOT Code begins with the letters "DOT" followed by a plant code (two numbers or letters) that identifies where it was manufactured. The last four numbers represent the week and year the tire was built. A three-digit code was used for tires manufactured before 2000. For example, 178 means it was manufactured in the 17th week of 8th year of the decade. In this case it means 1988.
For tires manufactured in the 1990s, the same code holds true, but there is a little triangle (Δ) after the DOT code. Thus, a tire manufactured in the 17th week of 1998 would have the code 178Δ. In 2000, the code was switched to a 4-digit code. Same rules apply, so for example, 3003 means the tire was manufactured in the 30th week of 2003.

The four digit dot code has been in place since the year 2000.
A three digit dot code was in place in the 1990's, pre-fixed with the < symbol.
Prior to this, dot codes were just three digits, the first two (as they are now) denoting the week and the last digit denoting the year. If your tyres don't have the arrow, they will be from the 1980's.

Here's two photos of the code. Maybe the arrow is that triangle after the code or the one just above the code on the lower photo?A three digit dot code was in place in the 1990's, pre-fixed with the < symbol.
