While Skyjacker claims that will work, you cannot fit a 285 tire with that wheel. Even a 265 will leave almost zero clearance to the upper ball joint.
If you do have a clearance issue, you might be able to get away with using a 1/4" wheel spacer.
The Rancho kit uses the exact same spindles, and Rancho recommends a max backspace of 4.5".

The exact measurements are as follows, 265/75/16 section width on a 7.5 inch wheel is 10.5, so if you mount it on a 8 inch wheel it becomes at most a half inch wider. In comparison a 285/75/16 on an eight inch wheel has a section width of 11.3, which at most could be an inch wider on a 16x9 inch wheel. The difference between a 4.5 inch backspace and a 4.75 inch backspace wheel is 1/4 quarter inch further from the spindle. So tell me how this guy, http://www.355nation.net/forum/members/1117-kraco5.html, runs a 285/75/16 procomp on 16x9 witha 4.53 inch backspace, and does not rub the ball joint? IMHO, the federal safety folks would not certify the skyjacker lift if the listed specs were wrong. As long as you have clearance, 1/4 or 1 inch you are not rubbing. Just my opinion based on the math.

The Rancho and Skyjacker kits specify 17'' wheels. RKJ is right on this one. Going down to a 16'' wheel brings the widest part of the tire closer to the upper BJ and results in less clearance. So, to summarize, if you go to a smaller wheel you need less backspacing. Also, there is quite a bit of variability in actual tire section width between brands and tires, so while some 285s might fit, others definitely would not.

Hell a 275 might even fit with a 16 inch and a 4.75 inch backspace. My original point was their instructions and web page say only that a 4.75 BS is needed. You have to actually open up their catalog and look up a page near the back of the book, to find an actual spec sheet that says a 17 inch is needed. With the right tire on his current wheel, he can clear a skyjacker lift and not have to buy new wheels. I have seen it done. That was his question, that is an actual answer to his question.
OP left out a critical part of the equation. Sound as if the wheel will fit but depends on the tire size as to whether or not there is potential for a problem.
Perhaps the OP can repost the question with all the necessary information so those guys can more accurately help him.
I'm confident that if he walked into a tire shop and asked that question, one of the first questions back at him would be "what size tire do you want us to install?"

Are you wanting to go bigger? If so you may, may have to change wheels. Not for sure on this, but it is a possibility.
