What does the DOT code indicate?

The DOT code, which stands for the Department of Transportation code, is a series of letters and numbers stamped on the sidewall of tires. It specifically indicates that the tire complies with all required federal safety standards set forth by the U.S. Department of Transportation. This means that the tire has undergone necessary testing and inspections to meet the safety criteria before it can be sold to consumers.

While the other options may refer to aspects of tire performance or specifications, they do not accurately describe the primary purpose of the DOT code. The code does not provide a direct measure of tire performance, maximum speed, or the age of the tire; rather, it assures consumers that the tire has been evaluated for safety compliance. This distinction is essential for understanding tire regulations and ensuring safe tire choices.
