Consider the class of matroids M with the property that M is not isomorphic to a wheel graph, but has an element e such that both Mne and M=e are isomorphic to a series-parallel extension of a wheel graph. We give a constructive characterization of such matroids by determining explicitly the 3-connected members of the class. We also relate this problem with excluded minor problems
