    I'm almost positive they are the same. Hope that helps!

    They are not the same. There are actually two types of telve bolt rims(a3350lb one and a 3850 lbe one) that even use different rings. If some one tries to tell you they are the same, go somewhere else. The twelve bolters actually use a thinner ring of a different diameter than the eight bolts. The two rims are so completely different in design the moment you put the wrong one in, you will realise the difference.b Use the wrong one, and you are guaranteed a leak.

    I agree. Im working on getting up pics of the differences between 8 and 12 bolt H1 wheels. The 8 bolts have a ring that comes off the front. The 12 bolts are an entire half of the wheel. The whole front of the rim comes off a 12 bolt. Hope this clears up a few things.

    Heres a clear pic of a stock 12 bolt that shows what blazd88 is talking about. Like he mentioned, I would think the O rings would be different since they come apart differently than an 8 bolt.

    the military versions were stamped on the outer rim piece with the load capacity. Another way to tell is that the 3850lb versions had a 13th hole in them for CTIS line routing through the rim.
