But if we cared about the people in the cars (wich I do), winter tires (studded or not) is number one priority.
If you use non studded ones they don´t increase road wear, but you could reduce the use of salt massively - alongside the frequence of plowing the road (also road wear).
If the risk of getting killed in an accident (in Sweden that is) decreases with 43% when using studded winter tires instead of non studded, what is the number if you use summer tires I wonder.
I agree with kombat, security for the people in the cars is the most important thing. If you really care about the enviroment - why drive in the first place?
