Hub Centric Hubbub: The Argument For — and Against — Using Hub Centric Rings with Your Wheels - OnAllCylinders
Depending on who you believe, hub centric rings are either: A) essential to the performance and longevity of your wheels, or B) a scam created by the wheel industry to …
...There are a couple of myths involving hub centric rings.
The first myth is that if you don’t use a hub centric ring, the wheel will never be centered on the axle, leading to uncomfortable wheel vibrations while driving. While it is more likely that the wheel will be off center without the use of hub centric rings, it is not impossible to center the wheel by following proper installation technique. However, Summit Racing recommends the use of hub centric rings to improve the ride quality of the wheel. The rings improve ride quality by holding the wheel centered while it is torqued down.
According to a second common myth, the weight of the vehicle is supported by the hub pilot mating with the center bore of the wheel. If you don’t use hub centric rings, you transfer the weight of the vehicle to the lug hardware, and the wheel studs will break.
Fact is, the hub centric rings do not bear a load. The weight of the vehicle is actually supported by the friction between the wheel and its mounting surface on the axle. The friction is established and maintained once the lug hardware is properly installed and torqued to specs.
