    No those wouldn't fit but you could probably find some in the correct 4.75 SAE or 5x120.65 Metric bolt pattern. I bought a bolt pattern tool for 3 bucks at the swap meet. It's a plastic wheel with the different pattern stamped on it. You could probably find one in SAE and Metric patterns.

    No, on a five lug pattern you measure from the outside of one lug to the center of the one across.

    That is an expedient way to get close to the bolt circle on a five lug wheel. Again, it's called a bolt CIRCLE for a reason... it's the diameter of a CIRCLE that all the bolts (or wheel lug holes) are centered on. If you have an even number of wheel lugs, then two opposite ones give you a diameter. There are no opposite ones with an odd number of lugs. I am constantly amazed that people find this such a hard concept to grasp.

    If you measure from the center of the the studs on our cars you won't come up with 4.75. It's called a bolt pattern not a bolt circle. Go back and read the link you posted. You have to go from the outside edge to the center of an opposing stud or you will have the wrong measurement. On four lugs you go from outside to outside, so if you used center to center it would be wrong also. I don't have a problem understanding this at all.
