ROAD GRIP OF WINTER TIRES ON ICE

VINTERDAECKS VAEGGREPP PA IS

The investigation is part of a larger project concerning studded tires carried out in 1988-89 by the Swedish Road Safety Office and the National Road Administration at the request of the Swedish Government. The results indicate that the improvement in friction on very slippery ice with studded tires can bring about a reduction of the braking distance to half its value without studs. Friction caused by the studs increased with the number of studs and their protrusion and decreased with wear. Roughening of the ice by studs improved friction considerably. Speed had little influence on the friction level. The results with different test equipments were similar under equal conditions.
