When a folding TM is set up, you can see that the upper half of each wheel is covered by a flat white plastic wheel well cover. The cover is held onto the body of the TM with two screws along the bottom edge, one in the forward corner and one in the aft corner. These screws have a square recess in the top, and a square-drive screwdriver (as opposed to Phillips or straight) is the proper way to unscrew it. (The tip of the screwdriver is male.) See this thread, and especially the pic in Post #6.

The folding TM has a lot of square-drive screws. Many of them can be screwed or unscrewed using a standard #2 Phillips screwdriver - but occasionally you run into one that doesn't respond, and it is easy to strip out the screw head. Now you have a problem. So it is a good idea to have the proper screwdriver in your kit of tools. They are cheap - see item 96615 at Harbor Freight, for example.
I assume (but I don't know) that the Elkmont is also assembled with a lot of square drive screws.
None of this is relevant to the spare tire rack. But you really should figure out how to remove the spare tire on your Elkmont now, while you are comfortable in your driveway. It is a much better way to figure it out now, rather than standing beside a busy highway.
