Noticed on my 1999 Ram 1500, 2wd that the rear hub bore is smaller than the front. By nearly 1/8" to 3/16" in diameter. So, from the factory the rear wheels on the back are non hubcentric. This seems odd to me, as I havent found anywhere that list a difference in hub bore from front to back. I found this out buy purchasing aftermarket wheels designed to be hubcentric that fit perfectly flush on the back, yet wont slide over the lip on the front. Ive attached pics for anyone not knowing what Im talking about.

I cant be the only one to ever notice this. No one has ever noticed this on their trucks before, and that the rear wheels are lug centric from the factory?

Thats odd. Last time I rotated my tires I rotated them front to back, next its left a right.

I don't remember having any problems.

Because your wheel center holes are bored large enough to fit the front, so you wouldnt have a problem.....other than the rear wheels being lug centric. Thats how my factory wheels center holes are bored.
