Wheel mounting Help

[JayDubBlazer]

Ok so I finally got some new rims. I measured them a couple times to make sure they would fit. So I wanted to test fit them before I take them off to the tire place to get the new rims on the truck. I have a couple of questions first. Is my steering knuckel too close to my rim? If so is there a spacer I can get to bump it out a bit? Second, my studs are not long enough for the lugs to touch them. Even if I had extended lug nuts I don't think they will reach, or reach enough to give me enough threads to get a good mount. I think they will work very well on the back given the wider axel. I posted a couple pictures to explain my questions.

Thanks y'all
