Its not a lot per wheel BUT over time each little bump on the road and that ammount pressing down will distort the expanded metal. At my job we use it and span less than 12 inches one direction but span about 36 inches the other direction. I suggest going to a place that either makes or sells ready made trailers and look at the distance that is spaned on those. My self I would not use this type of metal for the bed of the trailer. I like to use 3/4 treated plywood. The piece on my trailer is 8 years old and growing. With your bed size it would require two pieces tho. Maybe what you could do is put extra support under the mesh where the tires will be sitting when your cart is loaded so it don't distort the mesh over time. Good Luck.
