Mine were not hubcentric but the inside of the adapter was snug on the hub. If you really think about it, a lot of wheels with the two bolt patterns have an opening much bigger than the hub diameter and rely on the lugs to be center. As long as the wheel uses acorn lug nuts, the wheel should be centric. With that being said, im a over achiever and use hubcentric wheels and adapters when I can.
