A Toyota Prius has a mass of about 1450 kg without passengers. The car's instruction manual says to make the tire pressure 36 lb/in2 (PSI) or 248 kilopascal (kPa) evenly on all four tires. In metric units we measure pressure in pascals (N/m2) instead. The kilopascal is 1000 Pa, and the pascal is 1 N/m2. While there are many factors at play, the car is evenly loaded and all 4 tires are equally inflated to 248 kPa, how much area of each tire is in contact with the ground? What happens if one tire has half the pressure that is in the other 3
