Tyre DOT Code Inspection System by YAFE
Inline automated tyre marking inspection system reading and validating DOT codes on each tyre (tire) in real time — at full production speed using tyre sidewall OCR.
The Requirement
Apollo Tyres needed an accurate and scalable tyre DOT code inspection solution to ensure that every tyre (tire) leaving the factory carries a correct DOT code. Manual inspection could not handle the high production volume. Even a single missed error can lead to expensive recalls and safety issues. They needed a DOT code reader that could keep up with the line without slowing it down.
What YAFE Delivered
An inline automated tyre marking inspection system that reads and validates the DOT code on each tyre (tire) in real time while production continues at full speed. Using advanced tyre sidewall OCR, every tyre is verified without slowing down the line or depending on manual checks. The DOT code reader handles curved surfaces, embossed text, and varying lighting conditions reliably.

Frequently Asked Questions
What is a tyre DOT code inspection system?
A tyre DOT code inspection system (also called a tire DOT code inspection system) uses AI and cameras to automatically read and validate the DOT code on every tyre or tire as it moves along the production line. The DOT code contains information about the manufacturer, plant, tyre size, and week and year of production. Automated inspection ensures every tyre leaving the factory has a correct, readable DOT marking.
How does automated tyre marking inspection work?
Automated tyre marking inspection uses industrial cameras positioned along the conveyor to capture images of the tyre sidewall. AI software then reads the markings using tyre sidewall OCR and compares them against the expected values for that production run. Any tyre or tire with a missing, incorrect, or unreadable DOT code is flagged immediately for rejection or rework.
What is tyre sidewall OCR?
Tyre sidewall OCR (Optical Character Recognition) is the technology that reads text and numbers from the curved, textured surface of a tyre or tire sidewall. Standard OCR tools struggle with curved surfaces and low-contrast embossed text. YAFE uses custom AI models trained specifically for tyre and tire sidewall reading, achieving reliable results even in challenging lighting and at high production speeds.
Can the DOT code reader handle high production volumes?
Yes. The YAFE DOT code reader is designed for inline deployment at full production speed. At Apollo Tyres, the system inspects up to 15,000 tyres and tires per day without any impact on conveyor speed or cycle time. The system processes each tyre in real time and delivers an instant pass or fail result.
Does the system work for both tyre and tire spellings?
Yes. The physical product is the same regardless of spelling. YAFE DOT code inspection handles all tyre and tire types including passenger car tyres, truck tyres, OTR tyres, and specialty tires. The system is configured for your specific product range and marking requirements.
What happens when an incorrect DOT code is detected?
When the DOT code reader detects an incorrect or missing marking, it immediately sends an alert to the operator and logs the event with a timestamp and image. The tyre or tire can be automatically diverted or flagged for manual review before it leaves the production area. All events are stored for traceability and compliance reporting.
