| Yesterday I made the statement that '55.2 GMC 25x models 
did not have a dual rear wheel option.  I did some 
more reading through the Master Parts manual last 
night (yeah, I know I should get a life) and found 
that there was one option for dual rear wheels on 
a 55 second series one ton truck.  
The following information is from the Master Parts manual.
Year    Wheel        Tire         Tube or    Rear 
        size         size         Tubeless   Wheels
55-59   17x5.0       7.00x17      Tube       Single
55-59   17x6.0       7.50x17      Tube       Single
56-59   17.5x5.25    7.00x17.5    Tubeless   Single
56-59   17.5x5.25    8.00x17.5    Tubeless   Single
55-59   18x5.0       7.00x18      Tube       Double
56-59   19.5x5.25    8.00x19      Tubeless   Single
56-59   19.5x5.25    8.00x19      Tubeless   Double
 
The 19.5x5.25 was the only one piece rim listed.  I'm 
no wheel/tire expert, but I question that the 17.5x5.25 
wheel sizes were listed as multi-piece wheels using 
tubeless tires.
