There is a German Opel-manufactured bicycle in the Ulster Transport museum that has short springs mounted all around an inner rim with a metal outer band retaining them.
Apparently due to the shortage of rubber during WW1 which made pneumatic tyres infeasible but I also wonder about oscillations.

However, vibration also dissipates energy. My mechanics is inadequate, but they very likely optimized.
