Pressure In Gases Experiment Hypothesis: Using the recommended tire pressure will provide better gasoline mileage. When the tire pressure is lower than the recommended value‚ the surface contact area between the tire and the road is greater. This will cause greater friction and more energy is required to move the car. As a result‚ more gasoline will be consumed. When the air pressure of a car’s tire is higher than the recommended value‚ the contact area between the tire and the road is reduced.
