One option is the 8 lug steel wheel designed for heavy duty trailers such as horse and/or cattle trailers. The manufacturers will tell you they're not suitable for car/truck use, but that's just a fairy tale dreamed up by the ambulance chasers because of the lack of a DOT number stamped on the wheel. The bolt pattern is an exact match to the Stovebolt 8 lug hub, and an adapter or a spacer shouldn't be required when using those wheels.
