bolt pattern/hub question

[eekflyer]

I apologize if this is posted elsewhere.

Is "American bolt pattern" a 2.5 or 2.25 three bolt circle? Both? I have a set of Douglas wheels and need hubs.

I looked at these:

Hate to answer my own post...

I believe that the bolt circle is 2.5 but the distance between the studs are 2.25. So, "a 2.25 pattern on 3" (3 stud bolts)

If you anyone knows/cares otherwise, please advise.

Those hubs will work on your Douglas rims. They will also work on True roll rims.

Thanks for the help!

To answer your first question...

American Pattern is 3 studs on a 2/5" bolt circle. The center hub is 1.75" in diameter to locate the center hole in the wheel.
