For \(v \geq 4\) we determine the largest number \(f(v)\), such that every simple \(3\)-connected graph on \(v\) vertices has \(f(v)\) edge contractions which result in a smaller \(3\)-connected graph. We also characterize those simple \(3\)-connected graphs on \(v\) vertices which have exactly \(f(v)\) such edge contractions.
