Hi sbrady88! I'll try to help - I have an F150 but it may be the same as the F250 in this case.
Yes, I have hub centric wheels. That means the rim is centered on the hub & the lug nuts simply hold the wheel on & don't center it.
I have lug nuts w/flat ends & not the tapered style. I would think that if you have the same type of lug nuts you also have hub centric wheels.
Hope this helps!
I don't know how I missed this post.....but 4x4Cowlady is right on the money. Hubcentric simply means that the wheel centers itself by using the hub instead of the taper on the lug nuts. It's a much better system in my opinion.
