In the video, a person is seen holding a white marker and pointing to different parts of a tire. The tire is black and has white markings on it. The person is using the marker to draw lines and shapes on the tire, possibly to indicate areas of wear or damage. The tire appears to be mounted on a vehicle, as a part of the car can be seen in the background. The person's hand movements are deliberate and precise, suggesting that they are familiar with the tire and its condition. The video does not contain any audio or additional context, so it is unclear what the purpose of the markings is or why the person is doing this.
