Haha. Agreed. However these days a lot of new cars are coming out with rubber band tires on big wheels, and you can't tell if they're low or flat by looking at them. Their sidewalls are simply too small to see a difference.

Just before I shredded my tire (^above), the car did feel slightly "off", but I just assumed it was black ice since it was -20°C and the road looked dark/damp. It didn't wander all over the place like a typical 60-series flat tire.
