How to Measure
Install the Demo App and set it up for first use (see “How to Use the Tire Tread Demo App”)
Press Open Scanner
Position Device Correctly
(only on iOS) If on iOS, firstly
...
initialize the tire detection by moving device back and forth slowly (the camera should be pointing at the tire)
Align the
...
camera with the outer tire shoulder, keep approximately
...
20cm (8 in)
Once aligned, start the scan by tapping
...
on the screen
Move Device Slowly Across the Tire Tread
Move your device very slowly and steady towards the inner tire shoulder, always keep a distance to the tire of approximately 20cm (8 in)
The Scan will automatically stop after approximately 7 seconds; the device will vibrate strongly once the scan is done
| Info |

It is completely normal if the first attempts fail – we recommend doing a few practice scans to become familiar with the solution before performing real measurements. Follow the next section to get started. |

Finding the right spot to scan and get in the right position
You need to find a spot on the tire or vehicle where it is possible to move the smartphone around the tread from one tire shoulder to the other, with at least 20cm (8 in) of space. If the tire is not free-standing or the vehicle is on a lift, there is a very high chance that you have to kneel or squat to perform a scan. Just like it would be for a manual measurement using a gauge.
...
Get the movement right
For the process, imagine you are filming a video or panoramic shot of the tire tread. It is important that you record the entire tread - from one tire shoulder to the other.
...
Perform a practice scan and focus on recording from the outer tire shoulder to the inner tire shoulder.
Get the distance right
A scan should be performed at a distance of about 20 cm (8 in) to the tire. The vibration (and audio) feedback will indicate, if the distance is not ideal. If you feel the distance feedback vibration (or audio), adjust the distance of the device to the tire. The vibration feedback will stop, when the distance is correct.
Perform a practice scan and focus on keeping the right distance of about 20 cm (8 in).
Get the speed right
As with any other video recording or a panoramic shot, it is important to make
...
a stable recording that is as steady as possible. It is therefore important that the movement is slow so that there is as little motion blur as possible. The scan will automatically end, after the timer has finished - there will be a strong vibration. You can also end the scan manually by again tapping on the screen. Try to use as much of the time for the movement as possible.
Perform a practice scan and focus on making a slow movement and focus on the timer.
Get the angle right
The tread surface is the star of our shot, so it should be in focus of the camera, not the ground or anything else. We don't want to determine the tread depth of the ground, do we? Tilt your phone accordingly while scanning (pointing to the middle of the tire), this may feel a bit unnatural the first few times.
...
Perform a practice scan and focus on tilting the device to the camera points to the middle of the tire.
Get comfortable if you can’t see the screen
In some cases, it is not possible to see the screen during recording. There is a strong vibration at the start and end of the scan. Slight vibrations mean that you are either holding the device too close or too far from the tire.
Practice a few scans to get a feeling for it when you can’t see the screen.
Use the manual “Stop”
It is possible to end the scan manually by tapping the screen, just as you do at the start. You can use this feature to save time. However, it should not significantly reduce the scan time, otherwise you might receive errors.
Perform a practice scan and focus on stopping the the scan manually.
How to scan dual tires or tires next to each other
When scanning tires that are directly next to each other, it is important to make sure that only the selected tire is filmed during recording. This can be achieved by making a curved movement.
Dos, Don’ts & Scanning Tips
Use the Device Compatibility Mode if you are not using a “high-end” device on Android
Make sure that no other tires are visible in the scan, especially no tires should be directly next to or on top of each other, if you are scanning dual tires, record the selected tire only
