Is there any hope...?

Bought some tires and rims for a dang good deal! Went to go put them on and the back rims fit, but the front wont fit on over the hub? Is there any adapter or anything i can do? I measured the bolt pattern and they are the same but the center ring is smaller on the front tires then on the back. Is there another hub or rotor i can get to get them to fit?
