Wheel Stud Pattern

Hi Tony Z, I believe all 6 stud patterns are the same, but not 100% positive. As far as Landcruiser stud pattern that could be either 5 or 6 stud. Early model cruisers such as 60 or 80 series have 6 stud, but 100 & 200 series have 5 stud. Phil.

Hi Tony,

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.

I would question whether VSB14 being the Light Vehicle NCOP applies to trailers. There are plenty of boat trailers and box trailers that do not run spigot mounted wheels if you have a look around. I agree spigot mounting to the hub is preferable but on a motor vehicle you have far more loads imposed on the wheels due to steering, transmitting the drive to the road, rounding bends at speed, etc than on a trailer which just follows along being towed (or led) via an 'A' frame drawbar (hence the name "Dog Trailer"). PCD's do vary as does the stud hole diameter and the angle of the taper on the chamfered section where the nut seats. Also some chamfers are not just a straight line angle they can be "dome" shaped so you have to be sure the nuts match the taper otherwise instead of a full face contact the contact will be on a fine line and the nuts will come loose all the time. The other variable is the offset which is the amount the wheel centre disc (with the stud holes in it) is offset positively or negatively from the centre (in width) of the rim. Also when the nuts are done up tight the the angle of the chamfer centres the wheel on the hub and the hub spigot does not really carry the load, but rather assists the centralising of the wheel, because if the hub was to carry the load the wheels would have to be press fit and you would never get them off or be able to easily assemble them. On some vehicles with a bit of rust between the hub and wheel they need a good belt from behind with a gympie or sledge hammer to remove the rim/tyre.
