Can I fit a 33" or 35" spare on Factory spare mount?
Thinking about picking up either 33's or 35"s. Was wondering if either of these will fit on the factory spare mount, or will I have to get a new rear bumper and spare holder to accommodate the difference in size???

They will probably fit. The most you would need to fit is a spacer and several companies make them. The problem is the weight. The extra weight of a larger tire often causes damage to the tailgate, over time. The weight + vibrations separate the spot welds on the tailgate.

I have a Mickey Thompson MTZ
35" x 12.5" tire on the back of mine with a Mickey rim 4.5 backspacing no problems and no spacer needed.
Before that had a 33" Mickey tire/rim 12.5 wide no problem 2yrs.
It will work for a while but eventually will get a tire carrier too.

Both sizes will fit. You will need a spare tire spacer if you plan on running a 12.5 wide tire, but I would suggest a full size tire carrier. I ran a 35 with the mbrp spacer for about a year. The carrier made awful noise and bent my tailgate out slightly. No major issues but not to my liking.
FYI I've had zero issues with bending or breaking anything. Almost had it on for two years.

I had a spacer with the OEM bumper but don't need it with the Rugged Ridge XHD rear bumper. I have the tire stops but they created a pivot point. I need to find a way to brace the top or bottom. Or break down and finally get a tire carrier.

If you can Fab/weld then make your own spacer. That way, you can space it out and up the amount that you really need. I have done a couple of them. When I make them, I set it up so that when the gate closes, the tire is actually resting on the tire cut out of the bumper. And as for the rubber spacers, 3/4 heater hose will work. Just shove it inside the original rubber bumpers and cut to length need.
That what I have done. And no issues for 2 years now.
