I originally had the regular race deck and noticed that during the winter the water that got underneath took weeks to dry up. I don’t want Mold in the garage, so I switched the tiles to the free flow ones and the water is gone in a day or two. I use regular tiles around the perimeter to hold things together.

Any rubber tile that doesn’t allow for air flow is prone to mold if the slab gets damp. If you choose rubber, check every once and a while to make sure that moisture isn’t a problem. A guy posted pics of his rubber mat floor from Costco and it was absolutely covered in mold.
