You should be OK. Keep it tight so there's no vibration or wobbling. Make sure that rubber bumper is tight against the wheel.
If the wheel can move, it will start "tin canning" on the tailgate - you know how a tin can is strong when it's straight, but if it gets even a tiny crease, it bends really easily? You're avoiding that.
A heavy tire is a stress on hinges, but thats' not horrible, especially if you don't open the tailgate a lot.
Ill tell ya, for awhile I had a 35x12.50r15 attached to my tailgate stock carrier and it worked. The gate really started to sag and I had to go buy a rear bumper/spare tire swing arm before I jacked it up too much.
The three most common expressions (or famous last words) in aviation are:
- "Why is it doing that?",
- "Where are we?"
- and "Oh Sh!t!"
What is the maximum size tire that can safely be carried on the factory spare tire mount? Will a 32x11.5 cause problems or will I need an aftermarket holder?

I wouldn't put much faith in it. It will hold up a bit, but eventually you're going to start seeing cracks in the hinges, and your carrier might start pulling away from the tailgate. I'd just spend the extra money for a carrier, or keep it in the back and not even use a tire carrier.

I've been running a 33x9.5 for over 3 years now without issue. The key in my experience is to make sure the spare is snug against the tailgate and rubber snubbers. If it isn't snug, the gate will be subject to metal fatigue from jarring and vibrations.

I've had a 33x12.5 for 2 1/2 years. As indicated the snubbers need to be tight against the tire. With my rim back spacing, I needed to move the snubbers out 1" Hockey pucks behind the snubbers worked perfect. Additionally some people have made a lip for the spare to sit on. I have seen it done adding a plate on the bumber and I have seen a plate mounted on a hitch mount.
