Effect of tire pressure on fuel consumption - methodology and results (English)
Abstract [sv]

The objective of this study is to investigate what the real differences in fuel consumption are between recommended pressure and a pressure 15 percent below the recommendation. Further, the objective is to investigate the precision of air pumps at service stations which represent the equipment motorists use to fill their tires. Together these parts would indicate if it is possible for motorists to keep a recommended pressure in their tires in order to achieve possible fuel savings. The method used is based on field measurements on an existing, public road. Controlled parameters during the measurements included vehicle properties, tire properties, properties of the road stretch used, fuel properties and weather conditions. The results of the measurements showed that the fuel consumption decreased by 2,7 percent as the pressure was increased from 15 percent below recommendation, to the recommended pressure. These differences were independent of travelling direction (uphill/downhill) and were statistically significant at the 5 percent level according to a T-test. The precision of air pumps at service stations is generally good. Therefore motorists are likely to inflate tires to the intended pressure and benefit from fuel savings.
