I have a set of these tires on my winter bike and used them for several years with out any major stud loss or problems. In Icy/snow covered conditions you forget the road surface is an issue. This is not that much of a problem but the overconfidence you can get with these tires cans get you in trouble. The only down side I found with these tires is that they will tear up wooden surfaces as the studs cut holes in the deck. Other than that a great winter tire.
Bottom LineYes, I would recommend this to a friend
