Defender with Dynamic rims - you need to read this

[nugge t]

Like many other Defender Drivers, I fitted Dynamic steel rims when going to wider tyres. Unfortunately the centre does not fit snuggly on the axle hub with a 10mm gap.


This results in totally relying on the wheel nuts to hold the rim. If the wheel nuts are not tightened, or should they come loose the unsupported wheel will shear the studs very quickly.


This is the standard setup as we have all come to know it.

Recently several people in NSW have fallen crook of Transport. As a result Nugget Stuff put the shoulder to the grind stone and are pleased to introduce a Defender/Dynamic rim specific hub centric ring which over comes all of the problems.

CNC machined from steel and zinc plated to stop rusting, the Nugget Stuff Defender/Dynamic Hub Centric Rings are now available for $130/set plus post and are available from Nugget Stuff plus Mulgo and British Car Components.

Not sure but I suspect the rims are for another vehicle which has a larger hub and it is the only one available with the correct stud pattern/size to suit Defenders.
Let them know about the fix whilst you are talking to them :)

[Adrian18]

Have you a pic of the actual piece you supply ..not on the hub

No but I think this one gives a pretty good idea.


The chamfer on the leading edge helps when fitting the rim. The raised chamfer at the back is how the hub centric ring is held in place by the rim.

That problem would be the same on D1 and RRC and maybe the series models;)

[scarry]

Pro Comp Defender steel rims are also the same,they sit off the hub.

I wonder if the spacer fits them as well?

[nugge t]

Hi guys,


Happy to look at them if anyone in Brisbane is happy to be part of a development I am sure we can work something out for their trouble.

Dynamic rims are all made to be nut centric rather than hub centric as far as I know. I've had them on a few different vehicles and that's just the way they are.

This is a great idea as it makes fitting wheels correctly a lot easier. I recently had a new vibration at speed that was fixed by going over the wheels and refitting each one carefully which is a pain.

Will these fit the 300TDi Defender Nugget?

[bushrover]

Yep, Defender steel wheels centre on the studs, alloys centre on the centre spigot. Many steel wheels centre on the studs.

Mate I am not an expert on the earlier models but I have been told that the hub should be the same across most models??


If the hub is the same as the Puma's, they should fit. Maybe someone with a broader Landie knowledge can help us out?

[steane]

I reckon they'll be the same Nugget. I'll buy some and give it a try ;)

[Tombie]

Umm. Why?

Transport are obviously being morons! Steel rims on RRC, D1 and Defender are not hub centric from the factory...


Factory Wheels do not sit on the hub.


That is a requirement ONLY for Alloys..

[Tombie]

Factory steel wheels with factory nuts will centre when done up properly.

Aftermarket ones may not..

Maybe so, but I'd feel a lot better if the rim was supported by more than the wheel nuts. I was always taught the spigot of the hub was there to bear most of the vehicles weight - with steel as well as alloy.

Except the steel wheels are never on centre :)

And one of the reasons they run 16mm studs!!!!

[bee utey]

Hub centering rings are an excellent idea for making sure your wheels run true and balanced. However they won't support the weight of the vehicle at all times as they are not an interference fit on the wheel. Even if it's only 0.002" clearance the wheel will move on an occasional extreme bump. If I saw fretting marks around one of those rings I'd fit a new set of studs ASAP.

They certainly look great and if they keep the plods happy it's all good. :)

Dynamic rims in my experience can be difficult to centre correctly. If being able to centre them on the hub helps with fitting, what's the problem? I'm asking not being sarcastic btw.

It's not the first time hub rings have been used with Dynamic wheels. Same issues with Tritons and I've seen hub rings fitted to those.

Pretty sure there is a Puma build on Aulro where hub rings were required for engineering.

landie steels aren't hubcentric, once the nuts are done up properly the taper of the nuts holds the rim central o the hub.

if you loose the tension of the nuts you're still going to chew up the studs...

I'll give credit tho, the centering rings would make refitting the over sized ID rims easier.

but then what retains them and if they're press on items how do you pull them off i the event hat you have to run another rim for some reason?

[d2dave]

Dave. Go back and have a look at post five. There is a small lip at the rear of the ring making it a bit larger than the hole in the wheel.

[workingonit]

I would have concerns if the rear chamfer reduced overall rim contact with the hub ie became an object 'jammed' between the rim and hub. Otherwise good idea.

Regarding alloys, from the one vehicle I have that has alloys, the bolts are different to those used on steel wheels, and seem to be a more precise sliding fit ie alignment is still via the bolts and not the hub - happy to be corrected.

[nugge t]

The hubs are the same on the 300 TDi I am reliably informed.


The hub centric rings will not align your wheels or save you having to wheel balance. They will centre the rim when fitted so you are not relying solely on the nuts doing all the work and for anyone who has had Dynamic stlye rims will know this can be an issue.


For me the main benefit is if wheel nuts come loose. The ring will stop the "flopping" of the rim which will have an enormous shearing effect on the studs.


The fit is slightly tighter than the original steel rims which came with the 130.

It doesn't reduce contact at all. If you check a rim there is a slight rounding on the rim and the chamfer sits in area. The chamfer is just enough for the rim to retain it.

[nugge t]

Something else which I have not explained....


Generally people go to Dynamic rims so they can fit larger tyres. The larger tyres, either wider, larger diameter or both, place more strain on the wheel nuts. Many of us have had to loosen and re-tighten nuts to get the rim sitting correctly.


The hub centric rims greatly assist this regard as the rim is already centred before the nuts are tightened.

[Duarte19]

A bigger issue i have experienced is the actually wheel nuts

using the factory wheels nuts have the incorrect taper and eventually elongate the holes, in my case this caused a huge shimmy...

[nugge t]

The first batch of Hub Centric Rings are now in stock and going fast so get in quick.


They are not on my web page as it is about to be upgraded so drop me a PM, phone me on 0414 778 668 or email me at

This is correct. When you go to Dynamic rims, you need to get new wheel nuts from Dynamic that will hold the rim correctly.

[Tombie]

Nugget, I realise on reflection my earlier post sounds very negative. It was not the intent, as all I was stating is that the factory units weren't hub centric either.

What I would like to say is... Well done on finding the solution to keeping the authorities at bay... And with the added bonus of making centralising the wheels on these vehicles easier...

Good old Aussie ingenuity... Problem > Solution!

:cool:

[nugge t]

No problem mate. All good.


What I can say is that I have had a series of minor steering wheel shudders with Dynamic rims on both the 110 and 130. Having fitted them to my truck for the testing I can say that I have not had any issues since.


Again, the rings will not fix inherent problems but I believe that they assist in the following way....


Instead of the nuts having to do 100% the locating, the rings centre the hubs and the nuts only have to do the final bit.

With that in the light.


you havent done anything new here, this has been done before in other applications.

I personally disagree with your first statement that its a hub centric ring. Its not its just a centering ring. yes its a little semantic and picking on precise wording but thats one of those things that laywers and insurance companies love.


As a fitting aid however...

Iv seen people struggling to get normal landrover rims with big rubber on them to bolt up properly without killing the rim or the nut or the studs or if they do not getting them to torque in properly so the wheel comes loose in the next 10 Km.
. and I personally dont like the dyamic rims because they dont all like the OEM wheel nuts and while it can work if you pay enough attention its very easy to not pay that much attention and get it wrong.


Feel free to quote me on this so here it is in quotable form (assuming a set is 4 of the rings and the quote is used appropriately)

These centralizing rings are an aid to prevent miss fitting of your rims to your hubs prior to tightening up the wheel nuts and the potential outcome of that. As a device that minimizes the opportunity for error in an area that directly involves vehicle safety they're worth the $130

[nugge t]

Actually I don't think I have claimed to do something new. I have responded to requests from forum users. If I have given that impression, I do apologise but certainly on my build thread I have given credit to those who inspired me to do something.


Clearly a lot of people have an opinion on them. As I have said previously, they will not stop the need for alignment or balancing...hell they won't stop your mother in law talking but they do assist as described, in my opinion. People are free to form their own opinion and buy them or not buy them.


Thanks I'll probably stick with my quote as it is less lawyer speak.

Dare I ask... Do you make such a part?:D

[nugge t]

Mate I am working on it but somehow I think it may fall into the category of impossible dreams :)

[KzBushy049]

Do they fit a D1??? I have dynamics on my D1 and have the same issue with the massive hole in the middle. But that said they have been on there for 4years and there has been no issue. But it would look a lot neater .

Mate I am not sure. If you could send me the outside diameter of the hub we can see if we are in the ball park.


Alternatively if there is anyone with a D1 in Brisbane who is interested we could work something out. PM me.

[Blknight.aus]

it wasnt something that was intended to be used to replace your quote, it was aimed as support for your product.


Thats why I said you could quote me.:)



bbbbbbbbb

[nugge t]

Mate that is very kind of you. Luckily my mother in law likes them too only she hasn't supplied a supportive quote yet:)


I have had a very happy phone call from Matt on the Gold Coast who has had no end of trouble with wheel wobbles over a long period with his 130. He has changed rims, replaced rubber, steering components etc etc. British Off Road on the Sunshine Coast were doing some work on his truck in preparation for a Cape trip and as I happened to be up the coast at the same time I delivered a set of rings that he had ordered.


He fitted them there and then and after driving back to the Gold coast called me to say that he was over the moon as the wobbles had gone.

[Adrian18]

Well I fitted mine today all went well top job Nugget excellent service too the oil filter spacer is great also cheers mate
