what size rim for the F-70 - 14 firestone wide oval polyglass, 5.5" or 6"

[69 OUR/TEA]

I am going to run two sets of wheels and tires on this car ,magnums w/radials and bias ply w/the original hubcaps.I am going to be buying the F-70-14 Firestone wide oval polyglass WW"s to be used with the deluxe hubcaps ,but the rims that I have are 5.5".Is that what they were or are they supposed to be  6" wide?

All rims in 69 were 5.5" wide except the 15" Hemi ones. They were 6" wide.
