Dot dating tires
Department of Transportation (DOT) requires that every tire manufacturer provide a standardized identification number or code.
The DOT number is stamped on both sides of the tire sidewall and can be found by looking for the DOT designation on the sidewall.
It gives the date that the tire was manufactured but it doesn't just spell it out right.
You have to know what to look for and how to read it. It's on one side of the tire, so you may have to crawl underneath to look at the inside of your tires.
That's when you check the number or get ready to find another dealer.
