Damaged Wheel

I could never figure out why nasa used this type of material for the rovers wheels. it just don't make sense this is "Nasa" they should know how certain metals such as "aluminum" works after using it for many years here on earth we know that its a soft metal, but when we have a small car sized rover with all that weight riding on just aluminum metal something is bound to go wrong sooner or later, but better later than sooner. this should have given them an idea of what would be better suited for the job. I think nasa jpl should have done much more research into what would have worked better for a wheel other than aluminum, or using the aluminum along with something like a "carbon fiber" wrap over on the cleats of the rovers wheels, where they grab traction. this would have helped greatly to reduce the where, and tear on just the plain aluminum wheel. maybe they should have went with firestone, or Goodyear 100.000 mile warrantee. LOL. it does look bad, but if nasa could do a software adjustment so it keeps less weight off of those damaged wheels, and still work well then maybe it could go for another year maybe longer. I have no Idea just guessing. what do you guys think. is this it for our curiosity rover, or will this awesome rover keep going, and going like a 64 dodge dart 225 slant 6six.. thank you all. "god bless"

Here are three recent mastcam images of the damage from Sol 1179.
