Don’t let flat spots ruin your tires while your car is put up for the winter. Auto Care Products makes Park Smart Tire Saver ramps that cradle the tires while the car is stored long-term. They are made of solid PVC and are available in either 10- or 15-inch widths. Ribs on the top and bottom prevent the ramps from sliding on the floor while providing traction for the tire.
