Town Car wheels- Bolt pattern and offset?

I don't know what year town car came with these wheels, but I'm looking for info on them. The bolt pattern, offset, centerbore (if known), diameter and width. Thanks in advance :)

Hello

I can tell you for sure that my 1991 and 1993 Town Car has those same wheels.
