Yes, I know factory rims are 16.5. I'm upgrading to 1990s factory 16" inch steel rims. I'll be lifting the truck (suspension) 3 inches. I'm going for the factory hi boy look, with tall tires with aggressive tread in factory steel rims.

I'm looking for pics, input and suggestions on the best sized tire combo for this. It's in a 78 super cab 4x4 f 250

Thanks

 

Mid 90's F-series steel 8 lug wheels are 6 or 7 inches wide.

285/75-16 is a nice sized tire.
