*Because the 2011+ GMC/Chevy duallys have the larger 8x210 bolt pattern, the lug holes extend into the center bore of the semi wheels. The wheels must be notched on the inside of the center bore to accommodate the lugs. We offer this notching and/or milling service with our 22.5" wheels and 24.5" wheels. Please see last photo for an example of a notched wheel. If you have any questions regarding this service, please contact us
