ran 17" snow tires on the Fiesta Movement ST and would not do that for my personal car. Wheels were constantly packed with snow and the dealer butchered the factory wheels installing the tires. Everytime the dealer mounted tires on the factory wheels, they damaged them more. After 20,000 miles of hard use, the only damage on the car was from the tire installs, which we had a number of them over 6 months. The sidewall is also too small on the 17" tires to protect the wheel from damage. After 20 years of perfecting winter prep, I am 100% sold on having multiple sets of wheels and tires. Even on my wife's Escape, she has a set of winter wheels and tires and another set for summer. Oh, another reason why not to just swap tires on the same wheels is that each time a tire is mounted and de-mounted, the edges of the wheel are scraped by the equipment. Each scrape removes the clearcoat that protects the aluminum. Aluminum protects itself when oxidizing by creating a sacraficial layer on the surface. With the clearcoat gone, the aluminum forms a layer of oxidation between the rubber and the base material. This layer won't seal the bead of the tire and you get air leaks. To fix the air leaks, the tire needs to be taken off, the oxidation sanded down to bare aluminum, and new clearcoat added. No thanks, I will stick with 2 sets of wheels and tires. Also, the space required to store 4 tires is the same as 4 wheels and tires since the wheels sit within the diameter of the tire.
