Spare tire on the roof?

I am looking for options to mount a spare tire without rim on my motor home roof. If you are doing this I would like to know your setup also pros and cons.
Thanks,

    How is it mounted or secured?

    50K miles and it has not moved. It will get me out of a bind. This is from a old post so now 75K miles.

    Moved mine from the bumper to the roof. Tire and rim, class C 16". Pretty solid fiberglass roof. Got a piece of 12" square stainless steel plate, about 1/4" thick. Enough ss screws around perimeter to hold down, silicone in screw holes first. Had tire mounting bracket welded to plate first. After every thing screwed in place, laid 2 layers of heavy fiberglass cloth over everything. Will NEVER leak or shift. People comment about how to get it down if I need it. Gravity is your friend here. Getting it up the first time was not much of a problem, just slid it up on an inclined extension ladder. Only hard part is checking air pressure.


    Your method is a way I have thought about, but I wont have the rim, the two in my resort use brackets on the inside of the tire that are screwed into the roof. I like the idea of mounting like a sheet of metal first.

Tire has a heavy latch secured plastic and metal cover over spare to protect from weather exposure.
  • You asked for "also pros and cons". I don't think you're going to hear much because I don't believe it's a common practice, for exactly the reasons stated. I've never seen one up there.
  • Not looking for overall negatives or opinions of those that do not or have not done this. Please comment on actual experience.
  • Heavy, hard to get up there, not good on the roof, no good way to tie it down, sun damage are,just a few negatives.
