I understand these are a little hard to get, it took an LBS a month to get me a pair, so I thought I'd review them on my blog and share it here. I ride all winter and normally stick to the busy streets which are usually just wet. This year I decided to go with studded tires and Nokian A10 seemed to have the most practical stud pattern because they have 72 studs spaced along the outer edge of the tread. Most of the time the studs don't interfere much with the roll on pavement but provide extra grip in packed and rutted snow and ice. They are especially noticeable when turning on icy patches, then you can actually feel them grab and prevent the wheel from slipping out from under you. I've had numerous occasions already when I have stayed on my wheels rather than putting a foot down for stability. I still don't feel really aggressive on these, and I'm not racing across any frozen lakes with them, but it is a big improvement on the city streets. The studs are placed well enough that they help when you need them and are out of the way when you don't.
