Changing a tire on a TM

I'm investigating moving from our folddown (2003.5 Fleetwood Niagara) to a Trailmanor (looking at the 3023 model).

I have a question that I can't seem to find an answer for. How does one go about changing a tire on a TM. The pictures of the unit makes it look like it could be a very tight fit.

In the first 6 months of owning our folddown, we had to change 2 tires, drivers side, along a busy interstate. It was a very difficult chore.

Any thoughts would be greatly appreciated.
thank you!
