Some dealers or tire shops have a service to store/swap them if space is limited. You can ask around. There are really two ways to do it. A higher upfront cost of an entire set of wheels/tires. They just need to be put on. Other option is to have snow tires remounted on the same rims. This option costs more per change(mount/balance) but cheaper up front (no rims to buy).

I have an entire set and just use cheap rims. That way if you do slide into something and mess them up it’s not a huge deal. My stock rims are like $800 each…other rims are like $100.

I also downsized my tires to a smaller factory size. Usually cheaper tires on 17” rims vs 18 or 20”. If you keep the outer diameter the same you’ll get more sidewall height. That paired with the softer nature of snow tires will change the driving characteristics of your vehicle a bit.

My insurance agent of all people when I was a teenager said to find an empty parking lot full of snow and slide your car around. The first time you slip out shouldn’t be on a public roadway if you can help it. Stops you from freaking out and making it worse. Learn how to correct slides and such so when you need it then you have some idea of what you’re doing. Pay attention to light poles, curbs and more importantly…parking stones(the slabs of concrete at the front of some parking spaces that might be hidden under snow). So make sure you’re familiar with the lot. Back parts of mall parking lots are a pretty decent choice.

More stuff… While snow tires can help tremendously they don’t make it even remotely close to driving on dry pavement or even wet pavement from rain. You need to do just about everything slower and brake earlier.

Most snow tires have two sets of tread wear bars. The normal set found on most tires and a second much taller set that marks their reduction of ability when used in deep snow. You need more tread to disperse the thicker snow/slush. Biggest difference is the rubber followed by the tread patterns/siping. They stay softer in way colder temps than even all-season tires. The further below freezing you go the more noticeable this becomes. Conversely they don’t handle heat well and will degrade insanely quickly. The handling sucks too cause they feel kinda greasy because they’re just too soft at higher temps. They’re made for cold.
