Wheel studs are not designed to support the loads alone without the axle hub. I would much rather drive with hubcentric wheels missing 2 of the 5 lugnuts than multifit wheels with all its lugs but no support from the axle hub. It is not difficult to properly center a wheel while installing the lugs but there needs to be solid support from the axle hub. "Wheel centering rings" tend to be 1 size fits most & the metallurgy can be suspect. Do you want to ride on
" Made in China"?

Wheel studs are not designed to support any of the vehicle's weight. Hub centric rings function with aftermarket wheels to fit the hub so the weight of the vehicle is properly supported. The rings are "not one size fits all" - they're measured and manufactured to size (to the 1/10th of a millimeter) - that's the entire purpose of the hub rings. They allow you to center the wheel upon installation so the hub properly supports the weight of the vehicle. It's not any different than riding on any run of the mill cast OEM wheels that are "Made in China."

No car manufacturer agrees with what you say because the load is not "properly" supported it has been adapted with a temporary adapter.
.1mm tolerance I doubt it, what happens to the fit when corrosion alters it, & plastic you don't need to be a rocket scientist to predict the future of that.
One of the differences between adapter rings & OEM cast wheels is OEM wheels are DOT tested & approved. There is alot more load than just weight.

I knew this would be an interesting topic, and hopefully with some educational responses too.

Later I will post another thread:

Are you using hub centering rings with your aftermarket wheels? Yes or No

I can vouch for the tolerance because I have a micrometer and measured it myself when I installed them. No one is telling you have to put anything on your car - do what you want. For those people that DO want to run aftermarket wheels, there's absolutely nothing wrong with using a hub ring. I dare you to find an occurrence of a hub ring "failing." You're being a bit extremist.

True. Why not run them is the better question.

(bolded for emphasis)

wrong and wrong.

1. for certain applications they are accurate down to 1/100 of a millimeter. i personally run 66.1-60.1mm hubcentric rings, but they're listed as 66.06-60.06mm. how's that for tolerance?

2. aluminum hubcentric rings DO exist and ARE available.

It's necessary. Without 'em your steering wheel will vibrate even with perfectly balanced wheels and this causes accelerated wear on your suspension.

where do i get hub rings and what size do i need?

the information should be available on your wheels or at the wheel manufacturer website. you can also ask your local wheel/tire shop.

the lexus hub size is 60.1mm (60.06mm to be exact). depending on what hub size the wheels are, it'll be whatever the wheel hubsize is on the outer diameter and the lexus hub size (60.06mm or 60.1mm) on the inside diameter.

see my post above for a link to an online wheel/tire shop that sells hubcentric rings. most tire shops should carry them as well.

Where in my posts do I talk about a particular application or aluminum rings not existing?

projectdna

your understanding is not my fault, but allow me to explain.

i stated the fact that aluminum hubcentric rings exist and are available for purchase so as to address your concern that plastic hubcentric rings become brittle and altered from corrosion and what not.

I agree...but that would limit your wheel choices.

My understanding stems from reading every word in every post of a thread before commenting, perhaps you should try this

I order a set of WORK wheels for my 09 IS, do I need these hub rings? I knew there is more to it buying a set of wheels..
