You state the tile is 24" w 24", is that edge to edge including the cutouts for linking together? Also, curious to know how they hold up in freezing temperatures?

When interlocked, the size of our 6mm Energy Rubber Tiles is 23.25" x 23.25". So you will lose about 3/4 of an inch when you cut off the tabs. We do offer a tile calculator on the product page that will assist you in figuring out the number of tiles needed to cover your space. Our 6mm Energy Rubber Tiles will hold up just fine in freezing temperatures. Since they are made from the tread of commercial truck tires, they will not behave any differently than your tires in freezing temperatures.
