I too used to have a heap of issues with aftermarket alloy wheels and snapping/shearing wheel studs. Also had the rear left wheel come off one day while towing the camper along a corrugated dirt road.
I have since changed to factory alloys and will only do them up by hand using a torque wrench, not a rattle gun
From memory it was Snowie who used to have a lot of issues too, when the wheel nuts are tightened by rattle gun, it stretches the stud and will eventually fatigue and shear off.
Since changing to OEM alloys I've not had a single issue with wheel nuts/studs. Factory alloys are the only way to go for corrugated rough roads IMO
The weight of your vehicle would be contributing too. I had the alloy canopy on my tray filled with tools and gear for work, close to GVM weight (although I never went off-road carrying all this weight) I was replacing brake pads every 20k, went through a set of mickey T ATZ's in under 35k among other issues.
I've since changed the setup and removed the alloy canopy onto a trailer. Despite towing every weekday, the brake and tyre issues have all but disappeared as the vehicle itself is a lot lighter
And all wheel studs are the same ones that were on there when I removed all the weight, so all good there too
