A method for ascertaining a compaction state of silage stored in a flat silo, in which a work vehicle used for compacting the silage has inflated tires on at least one vehicle axle, includes in a first step, via an acceleration sensor, one or more of a normal and a tangential acceleration occurring in a tire bead is detected and wirelessly transmitted in the form of sensor data corresponding thereto to a processor unit, in a second step, starting from the transferred sensor data from the processor unit, the deformations of the tire casing occurring in each case during the rolling of the tire in an entry point and an exit point are ascertained and compared to one another, and in a third step, based on the comparison, a compression behavior and in turn therefrom the compaction state of the silage is determined by the processor unit.
