Actually, there are some design considerations if you are planning on driving over the aproximately 1.6" high bar that makes up the base of the goals. One of the things that I have been taught to do is to give your wheel a diameter that is at least three times the height of the object you want to climb over for best traction. You could technically do this with a diameter that is two times greater than (but not equal to) the height of the object you want to climb over, but for best results, the object you want to drive over should be 1/3 the height of your wheels. (Please correct me if I am wrong about this)

But back to your design, it looks like you have a good start, but I can't really offer any excellent input as I am also in the learning stages myself.
