Analysis and Evaluation of The Effect of Studded Tyres on Road Pavement and Environment (III)

In the economic evaluation of studded tyres their benefit and damage to the public was analyzed. Such aspects as the price of studded tyres, their effect on braking distance, fuel costs, road pavement, pavement marking, initiation of particulate mater and the increase in noise emisions were compared and analyzed. Based on the inquiry of tyre sellers and executed calculations, it was determined that in Lithuania, in winter season about 15% of passenger cars use winter tyres with studs, therefore due to the reduced number of road accidents (reduced number of people killed and injured) the public receives the benefit of 1.81 mln EUR. However, due to the more expensive tyres, increased fuel consumption, damages to horizontal pavement marking, negative impact of particulate matter on human health the public incur considerably higher losses amounting even to 38.43–39.07 mln EUR.
