I received this email from a client and I thought I should pass it along. I've never given "old tires" a second thought. And after watching this video, its quite likely many of us could be driving on old tires.
You can find the code that tells the manufacture date on your tires- it is a 4 digits in a rectangle after a string of numbers. (on some tires it is on the inside) They say that in the video, but only once. So, I imagine a lot of people missed it. You probably caught the code.
1 - Check the receipt they should have given you.
2 - Ask the store to view their records. Every tire should have a s/n and location record.
3 - Ask the guy that does your oil change and lube if he knows how to read it. s.
