Have you ever noticed spikes on the wheels of semis? They look pretty fierce.

Semi-truck wheel spikes are just simple corrosion inhibitors, meant to keep salt and grime from gunking up the threads on truckers’ wheel studs. The pointy appearance is just that — all appearances, a banal function given halfway interesting form.
The cover has function, but the spiked appearance, well that’s just for show.
