VW Beetle Tire Blowout
RAY: And that's the question, how did Helmut know?
TOM: And don't forget, in those days there was no such thing as this undersized little spare tire that many cars have today. All the tires were exactly the same.
RAY: Yeah, in fact the spare was exactly the same make and size and everything, and Helmut had never seen them before. And he probably would admit he was taking a guess.
TOM: That's what makes it interesting.
RAY: And he made the guess based on the fact that the windshield washer in the Volkswagen of that era operated on the tire pressure of the spare tire.
If the tire pressure dropped down enough, then the washer would stop working, and saving enough air in the spare so you could use it as such. But if you had a flat and you had no air whatsoever --
TOM: Then you would have no windshield washer.
RAY: And thus a mud splattered windshield.
TOM: Ho, ho, ho, ho, ho --
RAY: So who's our winner?
TOM: Ho, ho, ho, ho, ho. The winner is Antonio Otero from the Bronx, New York.
