Retracting Studs On Winter Tires

It would be great to have a set of these tires during the winter. The studs retract into the tire when they are not needed, which would be a plus because studded tires are very noisy on bare pavement. But when you need them for icy conditions the studs would extend out of the tire to give you extra traction. I remember when studded tires were allowed for everyone to use. That was one safety device that people willing bought and would seek out for their cars. But because of concern about pavement wear (one thing I heard many years ago is that pavement wear was based on a study of the pavement wear caused by horse shoes on Machinac Island) and now studded tires are limited by what type of stud and on what vehicle it can be used on like emergency vehicles or by first responders and mail carriers.

I do know that the studded tracks on snowmobiles can cause pavement wear. Where the snowmobile trails cross the highway they have put in a different type of pavement.
