Spin it and Space your whacks around the inside of the wheel. Did you install Dayton adapters? the truck in your link has disc/budd type wheels. usually the lugs are visible on a dayton set up. the nut holds a clamp which fills the space between wheel and spoke. on the rear once you get the outer tire off you have to slide the spacer off then you slide the inner wheel off.
