Our 8 to 10 lug adapters allow you to run the big semi truck wheels on your Chevy, Dodge, Ford and GMC 3/4 ton and 1 ton factory trucks. As the manufacture of these adapters, we designed them to mount semi wheels that use the 10-bolt on 285.75 mm bolt pattern. That means that you can go with a 19.5″, a 22.5″ or even a 24.5″ ten lug wheel!
