On one side of the tire, there should be a DOT code. The following can be found on Nitto's website (and others, I'm sure);
"The letters "DOT" certify compliance with all safety standards established by the U.S. Department of Transportation (DOT). This is followed by a combination of up to 12 numbers and letters.
The first two numbers or letters are the plant code where the tire was manufactured, and the last three to four numbers represent the week and year the tire was built.
Note: Recently it became mandatory to apply a partial DOT serial number on the sidewall opposite the complete DOT serial number. The partial DOT serial does not show the week and year that the tire was manufactured, but may still assist consumers in identifying tires should a recall be necessary. The purpose in applying the partial DOT serial number was to facilitate tire identification when the full DOT serial number may have been mounted towards the inboard side of the vehicle, and consequently not visible unless the vehicle was put on a lift for inspection."
