Are Hubcentric rings necessary....?
#1
I have heard for years that you should buy Hubcentric wheels or buy wheels and get hubcentric rings but, I've never actually owned a set of wheels that had Hub rings before. Is it really necessary? I know the theroy behind them but after researching wheels many appear to come with Plastic Hubcentric rings.? Is this plasic strong enought to really carry the wheel load and prevent slight missalignment of a lugcentric configuration? Just wondering if I should get them or just put $7 under each center cap for safe keeping....

2percooper is right. the hub holds the weight of the car and the lugs just
hold the wheels to the hub.
you don't necessarily have to have the wheels hubcentric if you dont race
or autox with them but it is a good idea to have the rings on there.
ive had wheels in the past that did not offer hubcentric rings but
not once did i have problems with the lugs breaking or anything like that.

Eight years ago I bought aftermarket wheels, from a big-name manufacturer, and had them installed on my coupe. For over a year I battled shimmies and wobbles, paid for several alignments and balancings, until I learned about "hubcentric". Turns out my supplier had unknowlingly omitted the hub adapters to make his wheels precisely fit my hubs. They sent the adapters, merely simple washer-type rings, I fit them to the wheels, and the problem was solved.

I bought a set of aftermarket 16" wheels with Bridgestone S03's for my wife's MCS and had a lot of intermittent shimmy coming from the steering wheel. I was about to send everything back until I thought to check the hubcentric adapter with a dial caliper.
Turns out the inside diameter was a shade under 2/10ths millimeter too large. The indicated size molded into the adapter was correct but it didn't measure up. I called the supplier and they checked their stock and discovered the whole batch was off specification. It took a couple of days for them to get replacements and forward them to me.
After I installed them, the shimmy no longer occured. I was amazed that such a small deviation from the proper size could cause such a noticeable problem regardless of how often I re-torqued the wheels.
Bottom line - don't mount wheels without the correct hub size or hubcentric adapter!
