Not to mention that any tire engineer will likely tell you that the tires are not designed to be driven with the load on that portion of the sidewall over extended periods of time (other than hard cornering). It's asking for all kinds of bad and unpredictable things to happen. And I'd bet that the majority of drivers with their cars set up like this are not experienced enough to properly handle the car when a tire pops off the wheel. I also wonder how often they check their tires for excessive wear to be sure they aren't worn down to the core.

However, you're right, it's their car and they can do what they want - I'm not arguing against that point. But when they are putting innocent drivers in their vicinity at risk, it needs to be called out for what it really is - stupid. When I encounter one of these cars on the freeway, I give them a wide berth and move ahead while mentally pointing and lauging a them.
