I am getting ready to store my car in my garage for the winter. I hear alot of people say they put their cars on jack stands to get the tires off the ground. I want to get my car as close to the back wall as I can. I am looking at getting 4 wheel dollies so I can roll my car into the corner. They seem like they would cradle the wheel pretty good so the tires do not get a flat spot. Does anyone on this site use them to store their car? Do you think they would ruin my tires?
