Method for determining the tread depth of a pneumatic vehicle tire and use of a mobile phone to determine the tread depth of a pneumatic vehicle tire

摘要

A method for determining the tread depth of the tread of a pneumatic vehicle tire, wherein in the tread at least one abrasion indicator (9) is provided which at least one extending in the radial direction incision (10, 10a, 10b), whose visible on the tread outside length with increasing wear on defined Way is lower and which has at least two fiducial marks whose mutual distance on the tread attrition remains constant and visible. By means of an application program of a mobile phone, in particular a smartphone, having a camera and a screen (22), a photograph of the incision (10, 10a, 10b) and the fiducial marks is made, the application program being made up of the defined distance of the fiducial marks and the length of the fiducial Incision (10) calculates the current tread depth and displays these and / or the remaining tread depth until reaching the minimum tread depth on the screen (22).
