	When driving, tires are continually deformed when the section of the tire that touches the road is flattened by the weight of the car. This can be seen easily it one looks at a parked truck. The flattening deformation of the tires causes them to heat up. The more the tires deform, the more [[energy]] they take away from driving. This is one of the reasons that sports and racing cars use tires with relatively small and stiff sidewalls - to decrease tire deformation.
