Hey guy's, what's up? Just a friendly Ford guy here
I am looking for some info for a non computer friendly friend that is almost done w/a total frame off resto on his 69 Z. He has kind of gone the modern route and and is now in search of some wheels. What he needs to know is for an 17 or 18" wheels what size width, back spacing and off set he should go with to fill in those wheel wells but not have to worry about rubbing.
Do a search - there are treads going here here right now with similar questions. This will get you started.
front 235 or 245 tire on a 8" wide wheel - 4.75" - 5.00" backspace
rear 255 or 275 tire on a 9" or 9.5" wide wheel - with 5.5" backspace
