21.   The heat caused the tire pressure to increase, making the tires more susceptible to damage.

25.   The tire pressure stamped on the side of the tire is the maximum pressure, not the correct pressure for your vehicle.

29.   Tire pressure and tire wear directly affect fuel mileage, and fuel mileage affects emissions.
