Quirying the need for hubcentric rings on my Work wheels.

 

My wheels have a hub bore of 60mm and the Subaru Hub bore is 56.1mm.

 

How many people run the hubcentric spacers and is it really required with such a small difference?

 

Work sell them in 60mm to 56.15mm for like $15 so it not big deal if they are needed.

I was just careful doing the nuts up bit by bit and the taper on the wheel nuts centre the rim.....I had no issue at all
Most aftermarket hubcentric rings are a plastic these days....and only for centering the rim...I highly doubt the take any load?

But yeah it wouldnt hurt thats for sure

Seen wheel studs sheer off without them.

They are a must.

Well there ya go...I should tell Grant to get some lol

Yeah deffs worth it


Any benefits differences between metal and plastic?

I've got metal ones on my RPF1's. A layer of anti seize on the side that faces the hub and no problems.

Plastic ones crack after a few years.

Hug rings just center the wheel, no load is placed on them. The wheel nuts and clamping force is what keeps the wheel from moving..I had plastic hub rings on my last car for over 30000km... theyre still in great condition...

You are keeping the load on the hub instead of the studs.

The studs are only to keep the wheel tight in place on the hub.

Your OEM wheels fit snug on this lip for a reason. If it wasn't needed the manufacturer wouldn't spend millions of dollars designing and testing to give you the lip

ive ordered some just because for the small price can be a big save

Hub centric rings are for ease of fitment only. The final locating and load supporting is done 100% by the studs and tapered nuts. The hub centric rings are made out of a variety of weak materials and are still a clearance fit, albeit reasonably tight. Furthermore, they barely protrude into the rim. The vertical load on a wheel does not bend the studs, it is supported by the friction between the wheel and hub produced by the clamping load of the studs. To bend the studs at all, there would have to be slip in this joint, which would mean it had already failed at its job. I see this argument pop up everywhere, it's not a subject open to opinion, this is how they're designed. Not saying they're not handy but certainly not required. Torquing up your wheel nuts correctly is the only thing you should be concerned about.

I agree with the above. I don't see how plastic rings could be stronger than the studs.

ooooh shit what have I done

Good info. 

I've seen what I've seen though...along with lots of vibration complaints that have been fixed using them. 

Buy wheels that fit or use them.
