Ayoob illustrated this point in the 1980s with an example of a Houston police officer who carried a SIG-Sauer P-220 loaded with 185-grain Silvertips and carried a separate magazine of CCI-Speer 200-grain "flying ashtray" JHPs. Based on his own experiments, he found that the Speer bullets deflated an automobile tire very quickly compared to the Silvertips. The day came when he was pursuing a car full of armed thugs. He exchanged the Silvertip magazine in his SIG for the one loaded with Speers while driving with one hand. He approached the BG's car from the right side, fired the Silvertip into their rear tire with little effect, and followed it up with six Speers that quickly deflated the tire and brought the subject car to a halt. While exiting his vehicle, the police officer reloaded with a magazine of Silvertips to back up the one Speer left in the SIG's chamber to cover the suspects until backup arrived.
That's one fast-thinking, fast-moving dude.
Incidentally, I'd love to be able to "experiment" to see what works best on blowing out tires. Much fun. ;-)
