> Well run flats, pressure sensors, and cellphones mean people very rarely have any need to change a tire on their own. Until they actually do need to change the tire. Typically, though - long before they notice - they become a footnote (and horrifying image) on "/r/justrolledintotheshop". Seriously - take a look at that sub-reddit - there are so many who know absolutely nothing about automobiles. For instance there's also a thread on some specific model car site about a guy who needed to change his oil, and somebody trolled him to flush out the old oil by running the engine and dumping -water- thru the fill hole and out the pan - needless to say, then engine was ruined. While they identified who told him to do that, nobody could believe that anyone who was attempting an oil change would do such a thing - but there you have it. It be like somebody asking how to restore a file they deleted, and telling them to remove the drive, turn it upside down, and smack it hard with a hammer, then re-install it. There are more than a few people who would actually do such a thing! And yes, I know about the old trick to free up an aging MFM hard drive...
