In the video, a person is using a digital caliper to measure the width of a tire. The caliper is placed on the tire, and the person adjusts the caliper's jaws to fit the tire's width. The digital display on the caliper shows the measurement in millimeters. The person then adjusts the caliper's jaws to take a second measurement. The video provides a close-up view of the caliper and the tire, allowing viewers to see the measurement process clearly. The person's hand is visible as they operate the caliper, and the tire appears to be a standard car tire. The video does not include any audio or additional context beyond the measurement process.
