The Stinger system employs high strength, hollow steel spikes that penetrate all types of tires – including self-sealing andrun-flats – and deflate them in a regulated manner.

And Stinger spikes are effective on all types of vehicles, including cars, trucks, and buses. See the spike replacement kit here.
