It is not a legal requirement to use winter tyres, but to "ensure sufficient grip". I would not dare to ride on rock hard summer tyres in February. You will for sure have snow and ice at the rally. You can use studded tyres here throughout the winter, even if Oslo and the main roads is covered in a miserable grey salt slush. (There is a tax for cars, but not for bikes.) The problem is that you cannot ride through Germany with studded tyres, and you should not expect to find a pair at the nearest shop. You could try here: http://www.snellingen.no.
Never seen anyone use snow chains. This is how another participant has prepared:
