Like I said in one earlier thread, you'll likely wear yourself out riding on bare pavement before the Nokian studs give up. That's the beauty of quality studded tyres, you can err on the safe side when it comes to riding conditions, and not have to worry about the tyres. It makes for a considerably tougher workout though.

If you have just one studded tyre, front is the place for it. Just like you're planning to do.
