USE OF STUDDED TYRES

OM ANVENDELSE OF PIGDAEK

Results of investigations show that: 1) Studded tires are effectiveness in increasing friction is greatest on frost-glazed surface when the temperature is close to freezing point when it reaches 100 per cent. On snow compressed by traffic, they are 30 to 40 per cent effective. These results are valid for driving, braking, steering and stabilizing conditions. It is emphasized that under the conditions mentioned the absolute values of friction forces hardly ever reach half of what they are when the carriageway is free of ice and snow. 2) On most road surfaces not covered with ice or snow, the use of studded tires does not result in a substantial change in the transmittable friction force. On concrete surfaces a reduction of about 10% is most frequently achieved, while on certain wet bituminous surfaces an increase of approximately 10% can be obtained.3) If half the total number of motor vehicles in Denmark were equipped with studded tyres, the annual costs to the Danish community would be approximately 120 million D.Crs.
