Sorry for the noob question, I just don’t want to mess this up! I am buying used rims and want to make sure they fit my sports trac. Thanks!

 

Coworker has a 2005 sport trac with 20 inch f150 platnum rims on, it fits fine but they do look a little large for the vehicle, 18s or 19s might look better size wise.
Keep in mind you'll need to buy a 5 lug to 6 lug adapter kit.
