I feel like an idiot asking this question but... I don't know what bolt pattern my car has.

It's a 1972 Plymouth Satellite, not sure what more information you need.
 
And that means you have 5 bolts that are on a 4.5" bolt circle or 114.3 mm.
 
Appreciate it fellas. I will now delete this thread to hide my lack of knowledge :)
 
If you ever wanna know for yourself, start with a wheel stud...any stud. Measuring across the chosen stud, skip the adjacent stud and measure to the center of the stud two positions away. This measurement gives you your bolt pattern.

A wheel hoarder friend said to me,
It's the outside of one hole, to the center of the other.
Looking at Don's diagram , that appears to be correct

True it would be 4.435" which with a tape measure would read about exactly 4.5"
 
Guys the proper way to measure depends on the number of holes. If the number of holes is odd then you have to do some math or look at a chart, or know by experience.
A bolt circle is measured to the center of the hole.

Being a machinist, I carried a 6" Starrett scale with me a lot. They have a 'hook' on one end and going from one hole (stud usually) across to the other side and measuring from the outside of one stud to the center of the one across from it would measure pretty much 4 1/2". If you measure in the same manner from one stud to the very next, you get 2 7/8".

Read post #14.....and the biggest obstacle would be if a wheel has a center cap that gets in the way but if it's off the car, you can measure from the back side....and the majority of the wheels for our old stuff is 5 hole.
 
I've taken an old hub from a disc/drum conversion with me to look at wheels before.
Then "if it fits it ships"

It could just be a case of "fat finger" syndrome, we all know it's happened before!

If people would check what they do before moving on, they could correct their fat finger 'syndrome' lol

this works out by coincidence, and falls into the category of “experience “, which the op doesn’t have.

That's to complicated for most people, the same goes for proof reading!

I'm guilty of not proof reading good enough lol and sometimes getting in a hurry isn't always a good thing.
