Hubcaps of the Undercover Highway Patrol

RAY: Full size hubcaps have a hole in them for the valve stem. That's where you put the air. And if the car's engaged in high-speed operation, it's possible for the hubcaps to come flying off. And when those hubcaps come flying off --

TOM: They take the end of the valve with them!

RAY: Right. The valve stem gets cut off and leads to rapid tire deflation… and an abrupt end to the high-speed chase.

TOM: It's not a chase anymore because one guy ain't going anywhere.

RAY: Do we have a winner?

TOM: Yes, we do. Our winner this week is Ruth Bogguess, from Port Byron, Illinois. And for having her answer selected at random from among all the correct answers that we got, Ruth is going to get a 26-dollar gift certificate to the Shameless Commerce Division at cartalk.com, where she can get an extremely skimpy Car Talk bikini.

RAY: What, we're selling bikinis?

TOM: Oh sorry, I meant a T-shirt. What did I say, I meant a lovely 100% cotton Car Talk T-shirt.

RAY: You're losing it.
