Ultra Spring Rover Wheel

My Rover wheel has a lot of springs to help it bounce over rocks. It also is made of tungsten and has springs made out of carbon steel. It does not have any air in it so it won't pop. I chose tungsten because it is super strong and could probably survive the rocks. And additionally, the tire is thick. On earth carbon steel would rust because of water, but there is no water on mars so carbon steel would be ideal for the springs.
