I’ve changed the curb side tire and the shells had to be opened for me to remove the tire cover and replacing of the tire. Now if for some reason your TM doesn’t have those covers, you might get away without opening the shells.
An FYI for you, if you do have a tire failure and the tire shreds some you’ll more than likely find rubber remains inside the bathroom wall area. As you can see in the second picture there’s a few things in the way.
