Submitted : Spring 2018

Efficiency of vehicles has been a big concern for many Americans in the 21^st century. In order to test how tire pressure effects this efficiency, 30 test trials were done. These test trials were consisted of filling the tires of a 2003 Honda Civic to tire pressures ranging from 40 psi to 20 psi. The car was then allowed to coast from 25 mph to 5 mph. After the 30 trials, it was concluded that the higher, 40 psi, tire pressure was more efficient and allowed the car to coast a larger distance.
