A Study on Vehicle Tire Inflation and Fuel Consumption

This white paper reports on an empirical case study carried out to examine the impact of tire pressure on vehicle fuel consumption. A case study with data obtained from Booster Fuels showed weak collinearity between tire pressure levels and the amount of fuel consumed by vehicles. The data comprised the make/model, license plate number, wheel tire pressure, fuel pumped-in, and the VIN for 30 vehicles for 2019, with information on at least two instances of tire pressure readings and fuel pumped-in. The data collected from Booster Fuels showed a very weak increasing trend when analyzed for collinearity between tire pressures and vehicles’ fuel consumption, signifying that low tire pressures can potentially cause an increase in fuel consumption. The weak collinearity is thought to be the consequence of insufficient data points used in the analysis. More data is needed to strengthen the linear relationship between the tire pressures and fuel consumption of a vehicle, which has been well-established in several other empirical studies reviewed and summarized in this white paper.
