Something I just ran into when I put the lift and some aluminum wheels on my DS, the rear studs were short and only allowed a few threads to engage on the lugnut. I just replaced all 8 rear wheel studs with 2" studs last night and it's much better. The front studs were fine in length, I'm guessing the thickness of the drum takes up some of the threads making the effective length of the stud quite a bit shorter than the fronts.
Carry-on trailer studs at tractor supply, part number 522T fit and work perfectly. 1/2-20 thread by 2" long. My local tractor supply price matched a website i found them at for $7.60 per pack too
Might want to check your wheels before bolting them up, some wheels may be okay, some are thicker and won't have many threads exposed on the studs when the wheel is onthe hub.
