It's a good hope to have, but I think you'll find a great many of us have had to change a tire at least once if not more often then that.
Many use, and I did as well, a 2000+ lb bottle jack. And I carried various chunks of 2x4 to use under the jack as necessary. Also, buy the proper lug wrench in advance.
I jacked my TT (back when I owned them) by placing the jack under the frame mount hanging down for the leaf spring suspension. I don't know if that's the correct place... but it worked for me.
Make sure to keep your tires FULLY inflated. You'll see a MAX Pressure on the sidewall and that's where to keep the cold inflation set. Tires blow out from under inflating not from over inflating. The manufacturer selects that tire for it's weight handling at that MAX pressure.
My TT tires said 80psi for Max pressure but I thought I knew better. I assumed that had to be too much. Wrong.
