If you get all-weather tires I would run them year round. For about the first 60% of their thread life they will be fine in snow. The next 20% they will be okay. After that run them through the summer and replace them before winter.

We have two sets of shoes for our buggy. 4x summer, 4x winter. All go flat, all the same size. When traveling we just toss one of the tires in the back with tool kit. If one goes, we have a real spare. Had to utilize that once when the tire was not repairable.

Why go that route? In short, anymore getting a replacement tire, run flat or go flat can be a PITA. Often taking a day or more to get it from the regional warehouse. With a RFT you may get back to a town but are really not going to go far. At least with a go flat and all the same size you can get home on the spare (think being in London on a weekend, trashing a tire on a Saturday, and the local shops saying they can have a replacement on Tuesday, but you need to be to work on Monday).
