DaveM Posted March 18, 2004 Share Posted March 18, 2004 I have been looking at Volks Alloys on the MVP website and notice that several of the models use Hub-Centric rings. Can anyone enlighten me as to what a Hub-Centric ring is and is it a good thing or a bad thing? Is it a spacer? Quote Link to comment Share on other sites More sharing options...
outatime Posted March 18, 2004 Share Posted March 18, 2004 The ring centres the wheels on to the hub. It is a kind of spacer that fits over the hub to makes sure the wheel fits correctly onto the the car. Lug Centric wheels centre on the lug nuts.

Chris Wilson Posted March 18, 2004 Share Posted March 18, 2004 It's a cock up to make a wheel that doesn't really fit centre on the hub spigot. Hub centric wheels should have the studs or bolts ONLY in tension, holding the wheel on, the load path and centreing should be through the spigot over which the counter bore in the wheel should be a snug fit. Makers often bore a big hole in aftermarket rims and use a ring to bring it down in size. Sometimes they are evn plastic, often they don't get used, or get lost. Buy a rim that is made for the spigot size of the car, don't use adaptor rings. IMO. Quote Link to comment Share on other sites More sharing options...
DaveM Posted March 19, 2004 Author Share Posted March 19, 2004 That's what I feared. Thanks for the help everyone, I think that rules out a few more sets of wheels. Quote Link to comment Share on other sites More sharing options...
Scooter Posted May 24, 2004 Share Posted May 24, 2004 ok i'm reviving this thread as the wheels i've just got (blitz's) would appear to be a manufacturer that does what CW says above and bores out the centre hub size. My wheels have approx 75mm bores and i've searched and found the supra's is 60.1mm. I'm just trying to find out if all blitz's are the same? I'm in the position where i can get someone to machine me some rings to slot in place, and in the big scheme of things i can't see being that big an issue, but possibly some people 'out there' have none on theirs and this maybe more of an issue? bobbeh, Seb, Matt..............anyone!

Scooter Posted May 24, 2004 Share Posted May 24, 2004 Matt pm'd back........ just re-reading the thread 'outatime' states this:- "Lug Centric wheels centre on the lug nuts." and CW this:- "Hub centric wheels should have the studs or bolts ONLY in tension, holding the wheel on, the load path and centreing should be through the spigot over which the counter bore in the wheel should be a snug fit." does the above mean that Lug centric wheels do not need to have a snug fit with the spigot? or should all wheels fitted to the supra be Hub centric? anyone know what type the blitz wheels are?....... .............. so many questions.................. and here's another, why are things never simple?

merckx Posted May 31, 2004 Share Posted May 31, 2004 It would be far too costly for wheel manufacturers to make their wheels to fit cars without using hub centric rings. It is perfectly okay to use the hub centric rings but you have to make sure they are a good fit so they do the job they are designed for. Aluminium or plastic are fine, the plastic ones have a high compressive strength and work perfectly. So don't just limit yourself to buying wheels that don't use the hub centric ring. From an engineering point of view they are fine- just make sure they are the correct ones. Quote Link to comment Share on other sites More sharing options...
sinbad Posted May 31, 2004 Share Posted May 31, 2004 Yes, just need to be careful when you are getting tyres changed etc. don't want to loose it or not get it refitted. Watching the monkey at work for peace of mind is necessary in any case Quote Link to comment Share on other sites More sharing options...
