"Studded tires take more lives than they save"

Written by Anna Wallin Adersjö Published in

 – The very function of tire studs, which is to save lives, can be questioned, says Anna Furberg, PhD Student, Mistra Environmental Nanosafety, at Chalmers University of Technology.

Together with Professor Sverker Molander and Associate Professor Rickard Arvidsson, she has conducted a study of the whole life cycle of tire studs.

The results show that the negative impacts on human health is larger than the positive, and that a large part of the negative effects occur outside Scandinavia.

Program Manager Julie Gold adds: There is a possibility of still using tire studs but replacing cobalt with an alternative element in the tungsten carbide cobalt alloys used to make the studs. Or developing different metal alloys or other hard materials that could replace the currently used tungsten carbide cobalt alloys. This could be a possible way forward.

Lab results from the Mistra program show some differences in effect of WC verses WC-Co nanoparticles, for example.
