Here are the most common 5-lug (1/2-ton) steel wheels, for 2wd trucks.

These are the 2wd 71-87 (and 88-91 2wd suburban) 15x6.5 steel wheels.
Hard to believe,... but these are getting harder and harder to find.
(like the 6-lug 71-87 version)

Notice the 4-nubs on the o.d. of the center ring?
This holds the standard 1/2-ton hubcap on.
