True or False: The DOT code must be molded on the sidewall?

The statement is true because the DOT code, which is also known as the Tire Identification Number (TIN), is a mandatory requirement for all tires sold in the United States. This code is molded into the sidewall of the tire and serves as a means to identify the manufacturer, the tire size, and the time of production. The presence of this code is critical for safety recalls and tracking purposes. Having it molded into the sidewall ensures that it is easily accessible for inspection, allowing both consumers and regulatory entities to verify important information regarding the tire's history and compliance.

The requirement for the DOT code is not confined to certain states or types of tires, which clarifies why the other options do not provide an accurate statement. It is universally applicable to all passenger vehicle tires to ensure safety and transparency in the automotive industry.
