This product helps to keep your tyres from flat spotting during long periods of storage. Once the tyres are set in the Flatstoppers (on a level surface), they will settle into the pad’s concave depression. More of the bottom portion of the tyre will be fully supported, thus dispersing the weight of the car more evenly onto the tyre and helping to prevent any flattening. Flatstoppers will not conduct heat or cold to your tyres despite changing floor temperatures, will not damage your floor in any way, and will not slide. Flatstoppers weigh only approximately 2kg’s each.
