How can i make this move and rotate properly in unity. Whenever i import it there it says "Can't calculate tangents, because mesh 'bezier circle' doesn't contain normals". Any tips, tuts? Thanks

Bake the animation.
Shouldn't the treads rotate the other way?
Well, actually when i apply array and curve modifiers this happens

Game engines have fairly strict rules as to what kind of aniations/rigging you can use.
You will need to have a chain of bones (if you don't care about performance, use 1 bone per segment - if you want to use fewer, the segments will probably bend)
Then parent your armature to your mesh and weightpaint your mesh (just google "Blender rigging").
Then attach your armature to your curve and animate the bones, preferrably in a way that allows looping.
Then bake the animation and you're done.

When do i make animation for these four wheels, after i make what you've said?

Same as with the segments. You attach each of the wheels to a bone and animate that bone so it turns at the correct speed.
