If you wanted to pierce YOUR OWN TIRE for some reason, if you place a nail under a tire, (assuming you considered roll angle) it would pierce a tire quite nicely.
Rubber would seal pretty well to make it a slow leak, but cutting a channel into the side with an angle grinder or dremmel would help.
For maximum air leakage, take a 1/4in or 3/8 in steel pipe, then cut it into 4 in bars, then cut those bars in half with a diagonal cut. Place sharp end into tire groove.
Again, this is for educational purposes only if you wanted to get air out of your tire very quickly.
you can just pick up a bb sized pebble, unscrew the valve stem cover, drop the pebble into the cover and screw it back on. The tire will deflate with no damage over the next few minutes. Free, easy, nothing to connect you to it if you kneel down to tie your shoes between the cars…

Please also remember that technically, there is nothing stopping you from buying a giant permanent marker
If you happen to accidentally draw a massive cock and balls on somecunt’s windscreen that would be unfortunate
