ABSTRACT:
An apparatus for testing a tire (10), which has a center (M), a width (B1, B2) which extends in an axial direction (z) and a diameter (D1, D2) on a tire plane (RME, RME1, RME2, MBE) which is orthogonal to the axial direction (z), is provided with a measuring head (20) which can be used to scan the tire (10). The apparatus also has a positioning means (30) which can be used to position the measuring head (20) in an observation position and to align the measuring head in an observation direction. The positioning means (30) can be controlled with the aid of a control and display device (40). The control and display device (40) has at least one control panel (44, 45, 46, 47) which can be used to input the coordinates of the position of the measuring head (20). Alternatively or additionally, the control and display device (40) has at least one display panel (44, 45, 46, 47) which can be used to display the coordinates of the position of the measuring head (20). The coordinates are determined using a coordinate system whose origin (0) is at the point of intersection of the tire plane (RME, RME1, RME2, MBE) and a roll axis (R) which extends through the center (M) of the tire (10) in the axial direction (z).
