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.
Video Demo
We also have a video if you would firstly like to take a look at our comparison demo!
To watch the tutorial, please click the video below:
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.
Let‘s see how a good example looks like:
Let‘s see how a bad 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).
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 |
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.
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 |
