Unfortunately, this is probably a leak, which is why many manufacturers have abandoned the spare tire on the rear wall concept and went with putting the spare underneath the coach or in a roto-molded compartment in rear storage. Quite a few have abandoned the spare tire all together.
Going down the highway creates forces on the spare tire carrier which ultimately elongates the bolt holes and eventually you get a leak. I would remove the spare tire carrier and investigate whether you have any water damage back there before deciding what to do next. Those that I have seen are usually pretty bad off before any evidence of water inside the coach is present. You certainly would want to repair any water damage as that would only get worse over time. You may want to consider an alternate spare tire mounting location going forward. Mounting on the rear bumper, under the coach, in rear storage or under the master bed are locations far superior to mounting on the rear wall.
