wheel adaptors

i for one would not like to meet a vehicle that has just lost a wheel and spacer on the highway.
i have also had two studs break on standard steel wheels, which are only ever tightened by me to the correct torque on my d1, this vehicle does have large tyres which i consider to be the reason, causing the added load on the stock studs.

I'm not convinced of this arguement. I'm sure somebody has done or had done these calculations and it was all clear. Was it Tombie???. If you compare the offset used by Land Rover compared to the wide tyres on other vehicles like on the Patrol and Landcruisers, the offset is nothing. In fact the Disco2/P38 have a negative offset, and 50mm spacers would probably reduce the stress on the wheelnuts. In addition to this, probably the nuts that hold on the swivel hubs on the classics would be more likely to fail well before the wheel nuts as they are smaller, run a smaller PCD and are further inboard of the wheel and outboard of the spring. I suspect it has more to do with the resultant steering geometry and the risks of too great a scrub radius when you hit things. The other issue I suspect is the talk of loosening spacers adaptors from differing expansion rates, and not being able to check them without removing the wheel.

I doubt if there is anything even remotely approaching a reasoned argument. Like so many other blanket rules, it is almost certainly the result of one or two well publicised accidents, where the use of wheel spacers was assigned some of the blame.

My opinion is that, and it has been this for a while, remembering I lived in Oz for many years is that, it takes intelligence to investigate and ascertain the exact risks and make a judgment according to the evidence available, it takes half a brain cell and the flick of a pen to ban something, therefore restricting our freedoms a little bit more everytime.
This banning attitude goes a long way beyond the small subject of wheel spacers.

I wanted a set of adapters to fit my land cruiser rims cos the tires are heaps better but they wont fit the disco series 1 rims and ive got 10 cruiser tires and rims sitting here and it would be easy for me to machine them up at work it would only take 2 or 3 hours but it just wasnt worth the POSSIBLE risk of them coming loose or snapping studs especially if my 3yr old is in the car with dad going to "play out bush"

I think we are on a whole other issue if you are going to make them yourself. As they are legal here you (a manufacturer) can have them tested and indeed they are, if you had seen the type of spacers we have here they are solid pieces of engineering.
Apart from that, converting from a 5 to a 6 bolt stud (and it has been done but only for show vehicles) is much more complex and not a practical proposition for a road going vehicle, and then you may run into problems with differing offset on a toyota rim I suspect.

This issue is a load of ****, firstly the nuts can be locked on with threadlock if you are worried by this, and there are many other critcal bolts in any suspension that I bet are never checked in the life of the car, and second, the bolting on of the wheel will prevent the nuts from coming off by physically restraining them, so if someone comes up with that tired old arguement, it is a non starter.

yep the toyota off set is negative which in a way is good as it gives even more stability than just the adapters. But then on the bad side you need to do some serious work to the guards because of the back spacing or else the wheel will come up into the side and do it for you. the other way i had been told was to weld the stud holes and the spigot then machine the spigot to the right size and mark the new pcd and drill the holes to suit but would still probably need some guard work too. or just sell all my cruiser wheels and buy a decent set of tyres which sounds heaps easier mabe just not as much fun.

You can buy some really nice wheels for Land Rovers over here, Might be worth looking at freight costs, these are one of my favourites at the moment
