Whether you are switching out summer and winter tires, or removing tires temporarily while working on a vehicle, these lightweight wheel stacking rings protect both the tires as well as your garage or workshop s floor. Simply pull your wheels off and stack them to the side on top of the rings. By using a Wheelstacker in between each wheel or tire, you ll protect wheels from contacting each other and scratching or chipping their paint. Using the rings also makes a stack of tires more stable and less likely to topple over when moved as a stack. These protective rings can help stop the build-up of dust and keep spiders and critters out of a stack during long term storage. WeatherTech's Wheelstackers rings come in a 24" round size and are sold in packs of four.
