Are tires with the date code of "510" and "520", no good? I think that means they were made the 51st/52nd week of 2000. Are they prob no good?

If they are "new you may be OK. It would depend if they were stored properly. In other words out of sunlight and away from electric motors. As already mentioned 6 to 7 years otherwise is about correct. Would also depend on how you drive the car. If you just putz around town compared to going sustained high speeds could also affect your decision.

yea, 6-7 is what most people say...but if they're stored properly they could last longer, but there is not a definite way to find out how they were stored.
ABC News just did a special on old tires:

Sears was selling tires like 12 years old!

In 2000, they changed to 4 digits. A tire built in the year 2000 will have a doube zero at the end, not one.

^^ That is wrong. It is number of weeks, then year code. Not the other way around.
The last three or four digits give the date the tire was made. For all tires built after 1999, this will be a four-digit number with the first two digits giving the week number, and the last two giving the year. For many tires built previous to 2000, the date indicator will consist of three digits, the first two giving the week number and the last giving the last digit of the year. In our example tire, the last four digits of the DOT code are 4501, so our tire was made during the 45th week of 2001.

And as someone else stated, if it's only a three digit code, it means they were produced before 2000....so that means they were actually produced in the 51st and 52nd week of 1990!! Please do not use those tires.lol
