You people seem to be missing the big picture here. We are talking about a Crown Victoria.

Not exactly the peek of performance. Basically a car that was donated or given at a cheap negotiated contract price from the manufacturer. Hence it needs all the help it can get, regardless of being a cop car or not.
Other than that thanks for the info. Good article but info sounds a little dated, I'll stick to what the car manufacturer says and not the tire manufacturer.
