Method for assigning tyre positions to a vehicle having a tyre-pressure-monitoring system, comprising the following steps: a) inputting vehicle data and vehicle tyre information with a mobile detection device, b) analysing the input information with the mobile detection device, c) conveying an instruction to the operator of the mobile detection device, wherein with the instruction the first vehicle tyre is displayed to the operator for the execution of a first tyre module identification process, d) positioning of the mobile detection device in the vicinity of the first vehicle tyre, which is predefined by the detection device, e) activation of an interrogation signal with a transmission frequency which is defined by the detection device and has a predefined signal amplitude, to a tyre module which is arranged in the vehicle tyre, wherein the tyre module comprises at least one sensor for monitoring the tyre pressure, wherein, when the vehicle tyres (1, 2) and / or twin tyres (1, 5) for utility vehicles are arranged directly one behind the other, the mobile detection device adjusts the signal amplitude (14, 15) of the interrogation signal in such a way that a correct assignment of the respective tyre module to the corresponding vehicle tyre is made, f) detecting a response signal from the tyre module, wherein the response signal comprises at least the identification data of the tyre module, g) evaluating the response signal of the tyre module and assigning the identified tyre module to a tyre position on the vehicle, h) storing the assignment of the identified tyre module in a memory of the detection device, i) indicating a further instruction to the operator of the mobile detection device, wherein with the instruction the next vehicle tyre is displayed to the operator for the execution of a subsequent tyre module identification process, j) positioning of the mobile detection device in the vicinity of the next vehicle tyre for the execution of a subsequent tyre module identification process, k) repeating the steps e) to j) until all the tyre modules have been identified and respectively assigned to a tyre position on the vehicle, l) transmitting the data which has been detected and evaluated with the mobile detection device to a central unit of the tyre-pressure-monitoring system on the vehicle, wherein the tyre-pressure-monitoring system respectively assigns a tyre module identification to each tyre position on the vehicle, as a result of which in the case of a tyre pressure warning message the respective tyre position on the vehicle can be displayed to the driver. a) inputting vehicle data and vehicle tyre information with a mobile detection device, b) analysing the input information with
