I picked up two a set of studded snow tires for my car. I just noticed they were two different types, they look almost identical, one is 2 months old and the other is new. I paid $150 for both. One is mastercraft the other is cooper. They are the same size in all, but will the different types of tires screw up my car or the way it drives? Didn't knwo where to post this, thanks. Hope someone can help.
