I live in the northeast and store my car for the winter. I wanted to know if anyone had any experience with a product called Tire Cradle which are supposed to prevent flat spots.

 

I have no experience with the product but I have never had a problem with any of my tires during winter storage. There is usually a thaw where the roads are dry and I can get the car out for a drive or two between December and March. Even in the worst of winters where the car might sit for 3 months I roll it a few inches forward or backward.

I have had success preventing flat spots by inflating tires to 55 lbs. and rolling car foreward and backward as Bigger Twin suggested.
