When people put obviously undersized tires on their vehicle. I’m not talking about doing it for aesthetic reasons. I’m talking about when somebody is too much of a cheapskate to replace their worn tires with appropriately-sized new ones and has the tire shop put on the smallest, cheapest ones that will fit. Don’t know why, but it bugs the hell out of me.

This one is clearly going for some sort of aesthetic effect, but it was too good to not use.
