I don't quite understand what your're stating or asking.

3/4 and 1 ton GM trucks typically have 8 lugs or studs at 1/2" and later 9/16" diameter with 6.5" bolt circle and if hub piloted 4.56" center bore, dual wheels are hub piloted.

I've not seen 2 ton trucks with this 8 lug pattern.
I have also not seen 5/8" studs used on this pattern.

You can learn some about wheels and bolt patterns by browsing the Accuride catalog, page 27 is a good start.
Perhaps wheel part number 29015.
