Traction-spiked Wheel

My wheel has spikes to have greater traction when the rover is driving so it can climb things better. The first part is a tube made out of aluminum that has bars. Where the bars meet there is a hole so you can attach an axle in it. The second part is thick rubber that goes over the aluminum tube and is glued on to it. The third part is aluminum spikes in fifteen rows and ten columns, and that's what gives the wheel better traction.
