What holds up dually wheels - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Once again I am a little "off topic" with a question about an 87 dual wheel chevy, But I am asking here because you guys know everything and I get more response than on the other parts of the board.

OK, I traded for some extra wheels for an 87 dually. The guy I got them from enlarged the center holes with a stinking grinder (yeah, really) to fit his Dodge. (every time this guy walks into the room, dualing banjos starts playing). My question is this. Is the load the wheel carry supported by the lug bolts or the big hole in the center of the wheel. I know on smaller trucks, the lug nuts are tapered and the lug nuts and lug bolts support the wheel, but the duallys have those plates that are basically flat. If you look hard at the lug bolts, there seems to be space around them.

I am putting these on a tool truck that never leaves the ranch, top speed like 15 mph, but I was just curious.

Thanks in advance

for what you said you were using it for i thinkyou will be fine. if your wheel falls off at 15 mph i don't think it would hurt much lol. but almost ALL factory wheels are hub-centric. meaning they are centered by the hub. even wheels with acorn styl lug nuts from the factory are hub centric. you won't find a factory wheel that has a bigger hole in the center than the protruding circle on the hub, they should all just fit around the hub and not be loose. after market wheels however are often lug centric.

Thanks,
I was thinking about an axle that isn't full floating, but I guess even that has the big round center that supports the hub.
