Abstract :
This paper deals with the importance of fuel economy in road freight transport. It provides the calculation of financial savings
for fuel savings of 0.5 l per 100 km. In the subsequent part, some factors that influence the fuel consumption are specified, e.g.
aerodynamic resistance, rolling resistance, and tyre inflation pressure. The effect of tyre inflation pressure on fuel economy has
been tested on four selected towing vehicles. Based on the results obtained, it can be stated that tyre pressure has a great impact
on fuel consumption. A one-bar pressure reduction of tyres can increase the fuel consumption by 0.5 l per 100 km.
