OUCH! This was very interesting, now I am glad we got rid of our stock wheels. In our case the 3500 Dodge SRW came with tires rated at about 3000 pounds each, I tried to find out what the wheel ...

I think the lug bolts don’t carry much if the wheels are hub centric. However, I have heard of bolts breaking if the wheels get loose.
Hub or lug centric is irrelevant regarding load. The load is carried by the friction between the wheel and mating surface. This friction is created by the clamping force of the lugs which is why proper torque on our lug nuts is important. This is also the reason you don't want any grease or oil on those mating surfaces.
"Centric" refers to how a wheel is centered while mounting. Hub centric wheels are good for manufacturing because the wheel can be mounted on the vehicle then the lug nuts just torqued down. With a lug centered wheel more care must be taken while installing and tightening the lugs.
