Has anyone used these (www.tirecradle.com) to prevent flat spots on your tires during winter storage.

At $299/set, they are expensive but appear to be a perfect solution for those snow free days when you want to run your car around town, i.e., no jack stands.

 

2 - 3 layers of thick plush carpeting cut to size will do the same thing. Get remnants and you pay next to nothing. But if $300.00 makes you feel better, go ahead.

 

also, pump up the tire pressures. That's free.
