How to compare the Anyline Tire Tread Scanner result to a Manual Gauge

This guide will help you to make a comparative analysis between the Anyline Tire Tread Scanner and a manual gauge. Follow each of the steps and contact your Anyline representative in case you have any questions.

Step 1 - Make a scan with the Tire Tread Demo App

IMPORTANT: Before you start scanning it is important that you know how to scan with the Anyline Tire Tread Demo App. To do this, please watch this tutorial: https://vimeo.com/774805672 Once you have mastered it, it‘s time to compare.

Select your Scan Area:

Start by defining a scan area of approx 20 cm on your tire (see below image as an example).

Perform the scan:

Scan from one tire shoulder to the other. Make sure to keep the right distance and don‘t scan for longer than 5-7 seconds.

Step 2 - Make sure that the scan was done correctly

After the scan, click the “Details” button on the result view and check the image on the PDF report for the following:

The image represents the tread profile of the tire (you can recognise the thread pattern)
The image clearly shows a good density of measurement points
The image is not skewed, distorted or shifted
Both edges of the tire are detected (there are regional results available)

If any of the above is either missing or not the case, please repeat the scan and check again.

Please find below a comparison between a Good Scan Example and a Bad Scan Example.

Let‘s see how a good example looks like:

Step 3 - Make manual measurements

Make 3 manual measurements for each main groove, in the area where the scan happened, and write down the results.

The number of grooves can vary, so we strongly recommend using the following device to make the manual measurements: Digital Tyre Tread Depth Gauge with Stainless Steel Body (39591).

In our example we made 3 measurements for each of the 4 grooves.

Step 4 - Compare the global results

Now we are ready to compare our results. In order to do so, calculate the average of all results from the manual measurements for each groove.

This is the value you should compare with the global result of the scan.

Region	Relevant Grooves	Manual Measurement	Scan Result	Diff.
GLOBAL	All (Groove 1 - 4)	AVG(2.70, 2.85, 2.41, 2.60) = 2.64 mm	2.70 mm	0.06 mm

In our example we get a global average value of 2.64 mm compared to a scan result of 2.70 mm.

Step 5 - Compare the regional results (optional)

You can also compare the regional results. Check the PDF report to see how the grooves of the tire were divided (by the vertical lines).

If multiple grooves are in one region, you need to calculate the average value of those manual measurements.

Based on the image in the report, we have to …

Calculate the average of Groove 1 and Groove 2 (because Groove 1 and parts of Groove 2 are in the left region) and compare it with the LEFT result
Calculate the average of Groove 2 and Groove 3 (because parts of Groove 2 and Groove 3 are in the mid region) and compare it with the MID result
Take the value of Groove 4 (because only Groove 4 is in the right region) and compare it with the RIGHT result

Using numbers from our Example:

Region	Relevant Grooves	Manual Measurement	Scan Result	Diff.
LEFT	Groove 1, Groove 2	AVG(2.70, 2.85) = 2.78 mm	2.80 mm	0.02 mm
MID	Groove 2, Groove 3	AVG(2.85, 2.41) = 2.63 mm	2.70 mm	0.07 mm
RIGHT	Groove 4	2.60 mm	2.40 mm	0.20 mm
