My mechanic who installs my snow tires offers a service to store tires for $12.50 per tire per season (about $50 plus tax for the winter). We store my wife’s tires since they are on rims; however, we don’t store them for my car (they aren’t on rims). My car’s tires are loose and tend to take up some space in my garage, which has been one of the reasons why my car would not fit into our garage (a double car garage).
Mrs. C8j noticed that Canadian Tire had a “Black Friday” (yeh right) sale on a wall-mounted tire rack for $56 (around), and I had been dithering about how this was going to be the year we try to fit my car into the garage (my wife’s van provides with little work), so it seemed like this past weekend we were going to try to fit both cars into our garage.
Saturday was the day. Thus we spent a reasonable amount of time throwing things out and then playing garage Tetris. Still, thanks to mounting my tires on the wall, some judicious destruction, and decluttering, my car fits into the garage.

The exciting part of all of this is that the cost of the rack is about the exact price as we paid for my wife to have her tires stored. So in some ways, this rack paid for itself if I had kept my tires (as you can see from the picture, I have other stuff that I can stuff into the rack).
At the end of it, we continue to play garage Tetris to see the optimal setup for the cars and the snowblower, but Mrs. C8j also points out that maybe we need a backyard shed to store the remaining stuff (others might say, have less stuff).
If you own two sets of ties, don’t you need 12 months of storage per year?
