I imagine that someone at the MOD picked up the phone and had a chat with Land Rover about stud length before ordering thousands of Wolf wheels to retro-fit to their fleet.
Perhaps the longer studs are more of an issue for 130's, particularly those plated at over 31/2 tonnes such as ambulances.
maybe not from my experience with the army in the 90s, they had issues when fitting transfer boxes in the the 300 type differ hand brake wise than the previous models but a transfer box for a landy was just that one part number covering different boxes,when fitting often theyd find an issue, so theyd keep fitting boxes till the correct one turned up, we use to modify the boxes to what they needed to fit, the guy said changing the number was more effort than the staus quo
 
Of course its probably complicated by the fact I have spacers so its not the original studs that will be holding on the wheels more the studs on the spacers?
 
I had exactly the same question when I wanted to fit wolf wheels to my 1985 110 (V8 Csw), so I asked my mate. This chap worked for 30 odd years in a research environment as a precision engineer +, the + bit being that he would design and make stuff to enable precision engineers to make stuff, if you see what I mean.
Anyway he was meant to be rather good at it, so I asked his opinion.
Reply as far as I remember was that ordinary original manufacturer stuff was in reality rather rough and ready, no matter how well they claimed to be making whatever.
As far as fitting wheel nuts, as long as all mating faces were clean of bulky contaminents (grains of sand/mud/rust whatever) then nuts that held the same or greater length of thread as the max dia of the thread on the stud would be well within safety limits. Maybe give them 10% more torque than normal,but no more than that.
Basically, just get on with it. That advice was for me to follow if I chose to do so. If you want to do the same then so be it.

As for the comments above about the military not bothering to change studs when fitting wolf wheels, I can't believe they didn't at least phone LR during a quiet moment and ask if it would work out.

They did - Land Rover and the mod then did a study and found they were safe with a slightly increased torque

Question.

Why will you need the spacers with the wolf wheels? Gonna look weird imo
