摘要
A method for determining the profile depth of a tread of a pneumatic vehicle tire wherein the tread has a wear indicator. The wear indicator has an incision extending in the radial direction of the tire. The incision has a length visible on the tread and the length becomes shorter as wear increases. The wear indicator has two reference marks at a distance from each other. The distance is configured to remain constant and visible throughout the tread wear. A photo of the incision and the reference marks is generated via an application program of a mobile phone having a camera and an image screen. A current profile depth is calculated from the distance of the reference marks and the length of the incision via the application program. The current profile depth and/or a remaining profile depth are displayed until a minimal profile depth is reached on the screen.
