Alloy Wheels on Bedford A truck

Seems to me it all comes down to older vehicles having nut centred wheels and newer ones having hub centred
VP of course had nut centred (tapered nuts and holes) so basically we had a new set of nuts made that fitted the bigger holes in the alloys and that did the centering. This was after new studs to cover the extra length needed for the thicker alloys as mentioned above.
As I said before, it gets expensive but personally I think worth it, and the difference in weight will be a factor when having to change one a few years down the track.

It's the look of the alloy style wheels I like.

Yes they are nut centred not hub centred. Most, if not all, of the modern alloy truck wheels I can find with 275mm PCD 8 stud are hub centred.

Busman, who did your wheel work?

Thats a story all in itself.
When I did a website for the build on VP so many came out of the woodwork we ended up with a buying group, one of the purchases was a heap of alloys out of China, about $190 each cause we bought quite a few.
Found a guy in Adelaide who could make some longer studs, trouble is he made them out of cheaper material and did not heat treat them, then promptly went broke, a few people got some breakages, most replaced those completely.
The nuts were made by an Italian company, but turned out they were Europe standard, 1.5mm smaller than our holes.
Long story short, we ended up at Australian Transport Spares in Brisbane who made us a complete set of studs and nuts, I gave them a wheel and they made the nuts to suit, so finally we have ended up with something safe and secure. If you wish to go there you need to speak to Murray Curti.
There was a couple of foul ups though when they were making from their files, sometimes used wrong file etc so had to make again.
If I was to do again I would make sure they had a wheel sample, stud sample and be very specific about what you want, even buy your "chromies" for covering nuts so nuts could be made to suit.
We also took the opportunity to go all right hand thread, dunno if that applies here, just a thought.

Hello Cam
We have trailers that require special wheels and therefore wheel studs as well. Our machine shop is equipped with CNC lathes and Machine Centres therefore production runs of wheel studs is easy. In our case we use 4140 steel, all of our wheel studs are used on spigot mounted wheels 22mm studs to suit industry standard nuts the wheels have 26mm holes which is pretty much the standard size for modern wheels.
The benefit in using 4140 is that it is 1000 MPA without heat treatment given that most heat treated studs only come up to about 900 MPA you save a process. For the record 10 studs per hub 4 hubs per row of 8 wheels up to 16 tonnes per axle line on Highway application, somewhere around 60 axle lines using our own studs made from 4140.
I am not aware of any failures with our wheel studs.

Me thinx ReX iz jist a stud @ heart
LOL

Hi,
maybe, just maybe the difference in the Hole is because they use different Nuts for the Ally Wheels than the Steelies. Like William said it will be a major Job for sure because of the extra Thickness of the Wheels.

Not really meaning to hijack this thread, but came across something similar myself. Have a few 18mm X 2mm studs that the threads are crook on, took a sample to a bolt specialist who cast around and although could find reference to replacement nuts, could NOT find anyone here in Oz who stocked them. (Industry standard are 1.5mm pitch fine, 2.5mm pitch coarse).Sent me to a well known engineer who does a lot of transport/heavy machinery repairs and was told that although new studs could be machined up in a more accessible thread form, he wouldn't do it for the simple reason that if there was a disaster like a wheel coming off and overtaking you, we would both be hung. Told him that the original manufacturer had been out of business for 50 odd years and even second hand parts are almost unobtanium.
His reply was that either I get some backyard machinist to do it (along with the risks involved) OR, I keep looking for an engineer who would warrant his work. Guess it was a case of he was either covering his own arse, or more likely didn't want to do the job anyway.
Not saying that the above posts are dodgy in any way, obviously in Rex's post re making his own studs in his own workshop would have exceeded even the most stringent manufacturers standards. But after reading a few pieces on tear-arse hoons having major disasters with wheel hub adapters, wheel spacers and the like, I reckon I would think twice before any sort of modification to wheels/rims hubs etc. OK if it is a straight swap to a larger wheel or a more accessible tyre.

When I first read your thread about fitting larger wheels my first thought was to suggest the
possibility of replacing your front axle and diff to a later model Eg(ford transit, f 350,Isuzu, dyna or similar) with the added benefit of better brakes.
