16" wheels on SSP car?

[Chriswoodard]

So in my quest for more history on my 1993 SSP car I contacted Ford and had them send me what they call a build sheet but it is basically just a listing of how the car was optioned during the build. I am confused b/c one of the specific options listed was "225/55ZR x 16" BSW All Season Tires". Could you order an SSP car with 16" pony sheels? I have never seen one. This car was one of the 30 cars that didn't go to Highway Patrol use in 1993.
