Hubcentric rings

[Bgibbs]

I know that there are pros and cons to this subject, but I installed a set of rings today. They totally eliminate the slop between the wheel and hub on our '16 Flying Cloud 26u. If you are interested, I got them from www.hubcentric-rings.com and the custom size is 102.0mm ID and 105.7 mm OD. They are actually made in Finland and take about a week or so to get.

Those are nice. Are they plastic?

Aren't the lug nuts self centering?

Interesting gimmick. My lugs are self centering, resulting in no slop.

Not a gimmick from an engineering perspective. The difference between hub versus lug centric has to do with how well the assembly withstands different directional forces. Lug nuts are designed to handle lateral forces that push the wheel away from the mounting plate. The forces that the hub and center bore connection are designed to withstand – the weight of the trailer forcing downward and impacts forcing upward – are at right angles to the forces that the lugnuts are designed to withstand. Lugs will be sheared off at a lower impact than hub centric failures.

Why do you think Airstream recommends checking lug nut torque multiple times after having the wheels off?

The reason I wanted to do it is because I balanced the wheels and minimized the road force variation with the wheels mounted on the balancer using a cone thru the center. I would be surprised if many shops have a 6-lug adapter for their balancer and do not use the center hole in the wheel.

If you don't know what road force is, google it.
