A: This question was posted on another forum, Crash Forum, i provided the following information:
From 1998 is an interesting paper which includes studded tires compared to others.
- Winter braking tests with 66 drivers, different tyres and disconnectable ABS
by Lennart Strandberg
Professor Emeritus at Linkoping University,
Vehicle Crash Reconstruction & Prevention Consultant
His new site STOP does not have English translations
I just did a quick search on 'studded tires' in my Reports section of my computer and came up with this report.
I have not reviewed the paper nor compared the results to other papers.
I mainly provide it for some additional information on the topic.
