They look like the hub was set up for super singles.
Effectively, there’s nothing holding the outer wheel on.

I was not impressed, and defected it… was I right or wrong ■■?
Wrong, those are retrofit nuts (the three little circles on the “washer” part of them tell you this) and therefore they are perfectly safe and legal.
The nuts will have been of the type shown in the previous image on this thread (the right hand nut) which has a long threaded sleeve that sits inside the holes in the wheels giving more than enough thread in contact with the stud to keep it safe.

I don’t want to worry you but the hub cap has a set screw missing as wellI have seen it before with Alcoa’s, but on a truck that had done nearly 2 million kms
The wheels are off one of our trucks that had just been sold, an 03 plate which had covered just under 1 million kms, I’m not sure if they were new fit on that one either.

This is an Alcoa alloy too, the cracks do look to have started on the inside.
Suedehead:
Looks like a case of brake bind or wheel bearing failure.
Either way,that wheel has got a tadge warm
I do recall the truck the wheels came off losing a complete hub on the A50 at Meir a couple of years ago, his O/S/F bearing seized and the driver only noticed when the steering pulled just as the lot ripped off and rolled away coming to rest against the barrier on fire.

I’d have thought those studs were a bit short as well. There’s normally thread showing.Maybe the thickness of the alloy causing that?
Well spotted
I looked at that after I saw your comment and you are right, I don’t know about UK laws since I left but it is positively the law that so many threads must show outside the wheel nuts. The mechanic who fitted these wheels should have know better.
I’ve never heard of that rule/law 
I did think wheel nuts were loose when I first started driving for these though.
We have eight 8 wheel tippers with the same wheels and nuts, most have been stopped by vosa at some time and never been pulled up on this, fly MOT tests too.

Not just alloys - I had a steel wheel on a 3.5 Transit crack in a similar way. Bloody glad I spotted it as it was a single on the front!
My boss says thy have had a steel crack like you say but never an alloy, He is on about contacting Alcoa to see if they can shed any light.
On our Foden’s with alloys we had the recessed type nuts and they were fine, we also had a few alloys crack as well but they were bought secondhand so could have been several years old. Losing wheelstuds was a problem with the front’s though, came back to Matlock from Wigston empty once with 4 broken, possibly to do with the front axle always being close or over its weight limit which was a problem when the truck was uprated from 24 to 26 tonnes gross.

aye ,over here in the great white north 2threads must show from wheelnut…overwise you will get a ticket if stopped by the DOT.and they notice …

So what was the outcome of you defecting perfectly safe wheel nuts? did they give you another unit or told you not to bother 
Like Paul said they’re perfectly safe, my unit has them fitted and it has passed several MOT’s, but Retro nuts need an alloy with a larger stud hole that allow the standard wheel studs to be used and can’t be used with a standard alloy.
The drivers CPC lark really has missed a trick or two concerning the intricacies of truck maintainance and the proper observation of tell tale signs that major components are about to fail, a skill that comes with years of experience but is something that can be taught and passed on. 
Hmmm, perhaps I should set myself up as a cpc trainer

Exactly, rather than all that twaddle which really concerns forklift drivers, construction workers, union officials and management. Who is responsible for reporting accidents at work, by when and to whom and what the name of the relevant law is sends me to sleep; how to avoid falling off etc - a different matter.
Accident investigations, more about load security especially evidence of why particular methods should be used and proof of why others don’t work, something about how driving and long hours effect health etc. would have been much better use of my OWN time.
below 72 pages all about alloy wheels, WOW. The contents page will point to the right sections about defects, studs and nuts.
