Well, upon further inspection of the rims/tires, I can't figure out which way they are supposed to go

. The fronts face one way and the rears the opposite way, which means that one set of wheels is the right way, while the others are wrong. I think the fronts are the right way and the rears are facing the wrong way, but I am just not sure. By looking at the pictures, can anyone tell me which way is correct?
