Could this flooring be used in a garage gym where we want to park cars when we are not working out?

You can use our 1-1/4" Fit Rubber Tiles as flooring in a garage gym where a car may park or drive over the tiles. These tiles are very shock absorbent making them great for Olympic lifts. Since these tiles are an interlocking tile, we recommend using a little bit of our Seam Sealer glue at the interlocks to keep the tiles in place. This will also help keep the tiles in place in the instance that you would have to turn the wheel when coming in or leaving your garage.
