Important limitations

This tool is a reference lookup for tire DOT plant/manufacturer identification records. It does not decode a complete tire DOT number, only the plant where the tire was made. It does not determine recall applicability, approve a tire for service, or verify whether a plant is currently producing tires.

This page is for informational purposes only on who made the tire and where. For safety-critical questions, contact the tire manufacturer, vehicle manufacturer, or NHTSA recall resources. Do not rely solely on this resource.
