Passenger car tires are not abused as much as truck tires.  Truck tires are
rated with a higher reserve capacity.  As I understand it, the de-rating is a
federal requirement.

Denis Haynes said: "Remember that when using a passenger tire on a
                   light truck, the tire should be de-rated 10%."

Why?
