The Mystery Mileage VW
RAY: The answer has everything to do with the tires. When this car was made, tires were not measured the same way they are now. They were measured in a typically American way, in which the width of the tire was one of the measurements. This car had something like 560-15 tires, which meant that the width of the tread was 5.6 inches.
It wasn't until about the mid-70's that they stopped making tires like this, and we went over to measuring tires in the metric system.
Now, if you buy tires, they might be 195, even though we also kept the 15 part. The 195 is the size of the tread, the 15 is still the diameter of the wheel, which is in inches.
There are also bias ply tires, but that's another story. Do we have a winner?
TOM: We do. The winner this week is Amy Bailey, from Philadelphia, Pennsylvania. And for having her answer selected at random from among all the correct answers that we got, Amy is going to get a $26 gift certificate to the Shameless Commerce Division of Cartalk.com, where she can get, among other things, a beautiful, blue Car Talk baseball cap, just in time for what? Football season.
