It's one of those bolt on adapters right? spray some PB blaster between the hub and the adapter, let is soak for like 15 minutes. unbolt the adapter from the hub. put the wheel back on, put a couple lugs on. use the wheel/tire as leverage. if that does not work it's sledge hammer time
Thanks guys for the quick response. Nothing is ever easy. Finally had to put my winter set on since I caught a nail with my tire last night. I had just put my 3rd tire on today and dropped the car. And it was a flat! All while in the pouring rain haha.
