Your tire inspection checklist needs to include tire scanning, and here’s why

Every DOT tire scanner reads the tire on the demo table. That tire is new, clean, and lit from the front. The tire that decides the purchase is on the left rear of a customer’s SUV. It is three winters old, with brake dust in the characters and the full code turned toward the axle.

Reading the code is the part every vendor can show you. Your tire inspection checklist also needs that code on the right vehicle and wheel, next to the tire’s size and age. The four types of DOT tire scanners differ most in that second part.

What is a DOT tire scanner?

A DOT tire scanner reads the Tire Identification Number molded into a tire’s sidewall and turns it into text. The number follows the letters DOT. It records the plant and the week and year of production. That gives you the tire’s age, and it lets you match the tire against a recall.

The code does not spell out the size, brand, model, load index or speed rating. Those are separate markings, so a tool that reads only the DOT code leaves half of the tire identification line blank. Our guide explains what each part of the DOT code means.

What types of DOT tire scanners are there?

There are four types of DOT tire scanners: consumer phone apps, TPMS tablets with a DOT function, drive-through lane systems, and inspection apps or SDKs for tire businesses. The table sets them against reading by eye, judged on what reaches your inspection record.

In 2017, the Tire Industry Association told NHTSA that retailers could not optically scan the code. Black letters on a black background, it said, are very hard to scan. The agency’s 2019 report to Congress looked at RFID tags and barcodes instead, and found that the RFID tags then in use did not contain the code. All four types read the molded characters with a camera, so they work on tires already on the road with nothing added.

Fixed readers on tire production lines form a separate category, built for the factory floor.

How can repair shops integrate DOT scanning into their tire inspection checklists?

Make reading the DOT code the identification step of your tire inspection checklist, at each wheel, between identifying the vehicle and measuring tread:

1. Identify the vehicle first. Capture the license plate or VIN at the start, so every DOT code that follows attaches to the right car and customer.
2. Read each tire at its wheel position. Save the wheel position with each code, so the next visit can tell which tire was replaced.
3. Capture the outboard sidewall. On tires made since September 2009, the federal tire standard requires the full code with its date only on the intended outboard side. The other side may carry a partial code without the date. If the four date digits are missing, turn the front wheels and read the inner face.
4. Record the tire’s identity with the code. Save the full DOT code, size, make, and model for each position. The four date digits give the tire’s age for the customer report.
5. Use the record after the visit. Match stored codes against recall notices, and raise tire age at the next service. NHTSA notes that some vehicle and tire makers advise replacing tires that are six to 10 years old, regardless of tread depth.

A shop without inspection software can use the TireBuddy App, which runs these steps as one guided workflow. A shop on a digital inspection or shop management system can ask its software provider to add the same identification with TireBuddy ToolKit. Our App vs ToolKit comparison covers which route fits.

Why choose the Anyline tire scanner for DOT codes?

Anyline reads the DOT code as one part of AI-powered tire and vehicle identification. On Anyline’s own figures, its DOT tire scanner is up to 300% faster than manual DOT recording. Each point below ends with a test you can run on any vendor.

One capture returns the code, size, make, and model

With one-shot capture switched on, TireBuddy reads the DOT code, size, make, and model from one image of the sidewall. The result adds the production week and year, the tire’s age, load index, and speed rating. Hand each vendor a used tire and ask for the size and the full DOT code from one capture.

Every code lands on a vehicle and a wheel position

TireBuddy ties every reading to the plate or VIN and the wheel, and the digital inspection report exports as a PDF or CSV. Ask each vendor to show you one vehicle record that holds a plate and four DOT codes.

Proven on tires in daily service

Anyline developed its DOT reading with Discount Tire, which now relies on it to process millions of tires. The app guides each capture by checking focus, distance, angle, and framing, and the software can read the code upside down. Bring three used tires from your own bays to the demo.
