Got my MB 72s delivered now. Got the 16x8.5s, but they came in boxes that said 17x8.5. Scared me for a few minutes until I took the wheels out and checked them.
These 16s only weigh 20.5 lbs. each on my scales! That is AWESOME.
Now I'm searching for the right tire (good offroad but LIGHT in weight...hard to find) and Monday I will hopefully have pics!

Finally... here are my pics.
Wheels are MB 72 16x8.5. They are listed as -6mm offset, but when I measured them with a tape measure they actually have 4.5" of backspacing which would be +6mm offset. Oh, well..can't expect the Chinese to get everything right. They weighed in at 20.5 lbs. each.
Tires are 285/75-16 Mastercraft Courser C/T (made by Cooper) 8-ply. They weighed in at 56 lbs. each and measure out 32.25" tall ON the Jeep.
Jeep is sporting Daystar 3/4" spacers for just a tad more ride height.
There is ZERO rubbing even at full lock. From the looks of things, when I get off road it's going to be a different story. I'm expecting fender flare carnage.

Your wheels do have a -6mm offset which on an 8.5" wide wheel converts to 4.5" of backspace. Check out this link...

Negative offset means the centerline of the wheel is closer to the inside lip of the wheel, right?
So a 8.5" wheel would have a centerline at 4.25 inches, and moving .25 inches closer to the inside lip of the wheel would make the final backspacing 4.0 inches.
But in actuality, these measure to 4.50 inches of BS, which means these wheels have POSITIVE offset.
See, depending on which tutorial you go by, you end up calculating offset in different ways. It's all very confusing.
Bottom line is... these wheels are PERFECT on the JK and I am very happy with the results! Thanks for this thread!!

So 8.5" + 1" = 9.5". 9.5" / 2 = 4.75" (wheels center-line). Take the -6mm offset (6 / 25.4 = .25") and subtract that from the center-line since the offset is negative and you arrive at 4.5" Backspace.
Glad you like the wheels

thinking hard
I just got my bonus in the mail and i am looking to get some MB72's. I have no lift (YET), I'm torn between the 15's with 33's or the 16's with 32's. I think both would be about the same price. Any idea on how much I would be looking to spend on 5 new spinners for either package? Also I know I have seen pictures of them, but the 15's clear an 07 NO problem right? I'm looking right now at Goodyear duratracs, BHawks4Life you still enjoying your set-up? Also did you guys all sell your old wheels? Wondering how much people are getting out of these stock 18's. I have a feeling I won't be able to give those things away I might just have a pow wow and burn those damn things
