With more info this post could be even more helpful

Accuride part number 28160 is for a 22.5" X 6.75" (tubeless) wheel with 10 lugs on an 8.75" bolt circle and piloted on the 6.25" bore.

The bolt pattern is larger than the AD trucks use 7.25" and smaller than common semi truck wheels ~11.25". I call the 8.75" bolt circle "medium sized GM 10 lug" but I may be the only one. It is for sure a GM only thing, and they are larger and smaller than other 10 lug options...
Looks about like this old one https://picasaweb.google.com/lh/photo/bDLWeU6bGkiAPaSd8yt3n9MTjNZETYmyPJy0liipFm0?feat=directlink



Accuride part number 28157 is a 22.5" X 6.75" (tubeless) wheel with 6 lugs on an 8.75" bolt circle, stud piloted "Budd" wheel (nominal 6.5" bore).

The 6 lug Budd wheels I think are still quite common to find used, so be sure to give it a good look before spending money on new ones.
