Computational resources can be used more efficiently by introducing reduced‐order models, instead of solving large systems of equations of the original model. In this contribution, the Krylov subspace method, a reduced‐order modeling method, is studied and compared to the modal decomposition for a rubber wheel model. (© 2014 Wiley‐VCH Verlag GmbH & Co.
