Optimally you'd like to have a switch on the bike that you press and tires change traction to that needed for the conditions on the ground on your current stretch of the road. Unfortunately, that is not going to be the case in any near future so you need to live with tires that are good on the average for a given day or few days. Since you may well find out that your plans are overly ambitious, there is presumably no point investing into numerous expensive tires. For ice you need spikes and most people start with lighter tires equipped with carbide spikes such as Nokian Hakkapeliitta W106. You may get one or two and always put the more aggressive studded tire on the front. If you find that winter riding works for you and you already have two 106s, you may get one or two tires with heavier thread and more studs.
The studs and heavy threads are slow on asphalt. The more aggressive tire, the slower it gets. I end up changing tires across winter, in the worst cases every night, optimizing the riding. I am down to 15-20 minutes with the change, but it is a pain. Another thing that you can regulate, also during a ride, is tire pressure. In winter you ride at low pressures.
