WK2 Wheel Specs

I've been toying with the idea of fitting a camper trailer with the same wheels and track as the WK2 so I've had to track down the exact wheel specifications which surprisingly is not that easy to find. You may benefit from what I've been able to glean. My reason for doing this is nothing to do with aesthetics just practicality in the number of spares that need to be carried. With older LandCruisers and Patrols it is easy. There are stacks of after market wheels for them but not so for the Jeep. One might think the Jeep's wheels are deliberately exotic to frustrate the after market suppiers. In fact they are not exitic, just current technology. They are actually remarkably similar to the current LandCruiser 200 series. Here is a table comparing the two:

___________________ Jeep_____________ LC 200
Wheel:_____________ 20-18x8"__________ 17x8"
Stud pattern:________ 5x127mm_________ 5x150mm
Offset:_____________ +56.4mm_________ +60mm
Hub Bore Diameter:___ 71.5mm__________ 110.1mm
Studs:_____________ 1/2"x20___________ M14x1.5
Hub centric:_________ Yes______________ ?

The offsets are near enough equal. Both have 5 studs. The Jeep's Bolt Circle Diameter is 127mm (5") whereas the LC has 150mm(~6"). The Jeep has 1/2" dia studs (12.7mm) as against the LC's 14mm studs. With the larger bolt circle diameter and the heavier studs, the LC's hub strength is considersbly greater than that of the Jeep. But then the LC has an additional 305kg to bounce around. It is 13% heavier than the Jeep.

That's brilliant Bob.
I have been toying with the idea of a 2nd set with some AT's on for when I actually go offroad. If I can't find a cheap 2nd hand set there is a wheel manufacturer not far from me who may be able to make some using those specs.

Cheers,
Matt

Did you see that Mopar Australia are now selling off-road wheels at their usual exorbitant prices https://www.mopar.com.au/Pages/Store/PartDetails.aspx?D=163 . I'm sure you could import them cheaper. There is a catch. They have described them as "off-road look" wheels. I think "look" is a weasel word for "fake" so I'm not confident they are any better.

Interesting.

Id like to get a new box trailer, but finding one with a suitable hub to take WK2 wheels is proving impossible.

LC, Patrol, falcon or holden (imperial) only it seems.

Is there a coverter / spacer available for the studs?

Don't know about the converter/spacer. Here is a US site that has trailer hubs with the right stud pattern at least Dexter;Quality;5on5;5 on 5; bolt pattern; 3500#; axle; hub; brake hub . I have Kimberley Kampers looking into it for me. They feel fairly confident they can come up with something even if it means some machining of hubs. I might have an answer when everyone is back on deck after the silly season. I don't expect it to be cheap and I may have to import the wheels myself. The cheapest I've found for OEM 18" wheels is $188.10USD each plus freight from Repair Parts: AllMoparParts.com . The freight would be at least double then there is the cap and wheel nuts.

I think there are several after market wheel manufacturers which sell their wheels without the stud holes drilled. They only setup the stud holes when the wheel is being ordered.
The problem, as I see it, therefore is not the wheel, but the hubs. If you can get blank hubs, in the same manner as the wheels, it should not be hard to match them all up.

While I'm waiting for the grandkids to get organised for Skpe and opening presents I thought I would pop in.....Merry Christmas to all (the Jeep got a new air cleaner and cabin filter!)

Bob you could try Melbourne Axle Untitled Document

Our off road van setup uses heavy duty hubs with 12" brake drums that fit over the hubs and studs - this is pretty standard with off roaders.

I used this company about 2 years ago to supply replacement 12" brake drums and backing plates with brake shoes, part of preparation at the time for a Gibb River road trip. I also purchased studs as spares..... - found the phone contact, service, price, quality of bits, and delivery of my order all excellent.

As they have their own workshop and do a lot of their own machining likely they will be able to help with supply of hubs to suit your camper axle. The brake drums would then be drilled to suit the hub stud pcd.

I would assume you would have your parts supplied to the camper trailer mob before delivery so the bespoke cost would be offset against their standard items. The outcome shouldn't be too bad if your camper supplier does the right thing.

Hi BobT,
This a really old thread I know, but I recalled that you had said something about matching wheels on a Kamper, and would like to know what you ended up doing.
I am looking at the Kimberley Kamper and the Tvan at the moment, and one of the issues is whether I can match the wheels and therefore carry less spares.
One potentially significant point was raised by the Tvan guy - he says that the Jeep wheels run on smaller slim line bearings than his trailers (and this probably applies to the Kamper too), and would therefore reduce the axle load rating. The difference in the hub bore diameters between the Jeep and the L'cruser you state above seems to support this view.
What did you end up doing, and what are your thoughts?
Thanks,
Russell

Your Tvan guy is quite right. You can read more on these and following posts, http://www.jeepgarage.org/f190/265-...le-in-lt-construction-50077-3.html#post795937 and here http://www.jeepgarage.org/f190/265-...le-in-lt-construction-50077-3.html#post795937 .

The axle was indeed down rated by KK to an Axle Load Capacity of 1,900kg but it was still more than adequate for the ATM of 1,600kg. The only thing that is lost is possibly longevity of the bearings. In any case, I replaced the obscure branded bearings KK used with Timken bearings which have load ratings considerably higher that 5 other brands I looked at.

Most cars now have encapsulated hearings with small hub bore diameters so interchange is difficult. For some silly reason, the trailer industry is doggedly locked into a 50 year old Holden/Ford wheel mind set. The benefits of having all wheels identical is that one can suffer two punctures and remain mobile whilst carrying two less spares. That's a saving of about 68kg not to mention the space.

Please note that the stud size shown in that old thread of mine you quoted, is incorrect. The studs are not 1/2" but M14.
