Thread: Six wheel studs to five wheel studs - why is it so hard?

The X5 rims have the same spigot dia and they also use tapered nuts. My spares are X5 so the van won't have spacers fitted for the X5 rims if not needed. I'll be making sure LR rims can be fitted in case I need to change back to LR rims on the vehicle or to another LR where the X5 rims don't fit.

Edit: 50 mm long studs at least as both rim/nut combinations can accomodate this length.

Call TRS in Adelaide. They sell them for $5 each and will ship for $10.

The only vehicle range to do that was the old 165pcd Land Rovers...

ALL 120pcd Landrovers use location on the centre spigot.

This is a legal requirement, and an important safety matter.

The spigot centres and carries the load, the studs just hold the wheel on...

cheers

We aren't fitting them to a Land Rover or any other vehicle range, they are going on a camper trailer, light van of half the weight.

As far as I know, no trailer/van or camper trailer on the market(single axle) has the hub to center spigot as the load bearer, they all have the wheel nuts to center the wheel and as the load bearer.

I'm not so sure about the trailers and vans being so light, with 1.4 tonnes on 1 axle being quite similar to a D3/4.

Everything you say is true, but 100% wrong at the same time, wheels that locate on the studs have a taper and a taper nut, Land Rover alloys do not, therefore the wheels are not located properly.

D2 nuts for alloy rims are tapered, because they are designed to locate steel rims as well, so if you had sunnies or speedy rims in a 120PCD you can use the D2 nuts.

BMW X5 rims have a taper and a tapered nut, which is what are going on my camper.

The rims I have on do not, but as there are no great lateral forces on a single axle camper and not a great deal of weight and they have been on the camper for 8yrs without a problem, I don't see the issue.

If I was putting them on a 4WD that would be a different story, but I'm not.

We could go on forever, but I'm not going too, so that's me done.

Argue all you want, or dont.. Laws is laws...

My boat trailer is 2300kg unladen (empty tanks, no gear)

The hubs pick up the centre hub.

Friends caravan does too...

Its Law... For these to do be like this... Just because you got away with it doesnt make it safe or legal....

From ExplorOz... This guy had to go through hoops...

I have just had enormous problems with this issue. I bought a new camper trailer which was supposed to come with wheels compatible with an NM Pajero (16"). I won't go into the whole thing but briefly they couldn't fit hubs to the trailer with the 67mm hole as those hubs would be weight limited to too low a figure. So they fitted hubs requiring wheels with a 105mm hole - so the Pajero wheels wouldn't fit. Once they sorted out the different offsets we found that it is illegal to run 105mm hole wheels on a 67mm hub, even though they will fit. This is becasue all the weight is then taken on the studs, not shared with the hub. (This was established by the Technical guys at the Deft of Transport with documentation to back up their viewpoint.

So, you need to match stud pattern, offset, and centre hole to be able to interchange legally. The key thing here is not that you are likely to get caught but that you will nullify your insurance.

Incidentally the Tyrepower agancy the trailer seller sent me to had no idea that it is illegal to run the big centre holes on the smaller hubs and the guy was doing precisely that on two of his own vehicles.

Here is one of the places the Technical guys at DoT looked at ...

Vehicle Standards Bulletin 14, section LS Tyres, rims, suspension and steering (Jan 2011)
This says in one place : " Replacement wheels must be designed for the particular hub/axle and have the same bolt/stud pitch circle diameter and the same centre location method."

They also referred to the 'Universal Tyre Fitment Guide' which says something similar - I think it refers to centre hole size rather than 'centre locatiuon method'. The bit that says 'must be designed for the particular hub/axle' is very clear - obviously a 105mm hole has NOT been designed for a 67mm hub.

The RAC in WA advised me that using the larger hole rim would not be legal or wise.

Common not to follow the rules, but definitely there are rules...

And load and cornering forces still apply to trailers...

It may work, just like having children with your sister could, doesn't make it right.
