What does the first and second grouping of letters or numbers in the TIN represent?

The first and second grouping of letters or numbers in the Tire Identification Number (TIN) represents the manufacturer's assigned identification mark. This is crucial for identifying the specific company that manufactured the tire and is part of the safety and traceability standards set for tire production. Each manufacturer has a unique code that differentiates their tires from others in the market, ensuring that any recalls, safety notices, or warranty claims can be easily linked back to the correct producer. The TIN is essential for maintaining transparency in the automotive industry and allows consumers and professionals to verify the origin and compliance of a tire with safety regulations.
