To assist students in becoming wise energy consumers by understanding how to increase a vehicle's MPG by performing preventive maintenance. Understand that vehicle maintenance can save fuel and money. Tires are THE control of a vehicle. This is commonly referred to as traction.
Traction is a result of many factors.
Among the many factors that effect traction, the most important are the weight applied to the tire and road, the condition of the road, the condition of the tire, and the amount of surface contact between the tire and the road. For a given size of tire, any increase or decrease in weight will result in a corresponding change in traction. As a road becomes more or less slippery, so does traction decrease or increase. Surface contact between the tire and the road is a factor of tire size and shape as well as tire inflation. For a tire to have its maximum designed contact with the road it must not be either over or under inflated.
