I bought some OEM Ford wagon wheels 15x8 (white spoke) 5 lug with the three screw holes for the black Ford center caps. I am going to put them on my 1979 F150 4x4. In researching old ford catologs and brochures it looks like Ford used 15x6 wagon wheels on the F150 and 15x8 on the Broncos, that is 1978-79. Does anyone know for sure? I did see a few pictures of the f150
4x4 short box and step side f150 with the 15x8 wheels, but most of the 2wd and 4x4 long boxes had 15x6. Anyone have picture of Ford OEM white spoke wheels 15x8 on a 4x4 f150. I think they will look realy sharp and nosalgic ?

 

I have 15x8 wagon wheels on my 2WD, but they're not factory; they're Cragars. Hopefully this gives you a frame of reference though.

 

Take a look in my gallery, my truck has 15x8's.
