Question to all Vision 19.5 wheel users
I was doing my pre-camper load up tire pressure ,check lug nuts torque etc. when I came to 2 lugs that didn't seem right. I was not able to get them to spec's. As it turned out it appears that the sho...

Lug vs Hub is primarily about centering. Once the wheel is mounted the bulk of the load is carried by the clamping force.
Their FAQ is about centering which deals with balance and not the load.
That is also a genertic FAQ and I found that the ring was not advisesd/required with the Type 81's. Vision doesn't even sell rings that would work, which they would if they thought they were required. They are talking about car wheels, which is what they make adapter rings for.
Tamnative, I have found most hubcentric applications to have 0.1mm of difference between the hub and wheel bore. Becuase there is no other method of centering it has to be very tight.
It always amazes me how many people think that the load transfers to the hub bore. If there is a gap, and there always is, even 0.1mm is a gap, then the load isn't being transfered to the hub bore. If the hub is touching on one side it isn't on the other and the torque on the lugnuts keeps the wheel from moving the bore to the hub as you drive.
The lug nut clamping force is what holds the wheel to the WMS under load.
If you are having vibration problems then look into a ring, but most rings are nylon, plasitc, or thin aluminum which further disproves their load carrying abilities.
Nice write up and 100% correct.
