Metamorphic Tires

My tire design will be able to shipshape itself to the different terrain. I made picture #1 to show a, tire for common MARS terrain, this one will be used the most. Picture #2 that can be programmed to shape shift with spikes for quicksand and soft sand because the rover has gotten stuck in quicksand a few years ago, this can get the rover unstuck with the spikes. My tire #3 is a shape shifting tire that can be programmed to shape itself to a triangle tire, so it can drive and climb on rocky terrain. I also think that the rover should have a spare tire under its body where the arm can be programmed to change a tire that has stopped working. The body of the rover should also be programmed to be able to tilt itself towards the sun, instead of driving around for solar power.
