It seems you have 3 choices for safe tire replacement. If you're hooked to your tow vehicle it's easiest to simply lay down a ramp and drive one axle at a time onto the ramp which will raise the other wheels off the ground. Safe and easy. Otherwise you will simply jack it up. Some use the axle mounting plates as a reinforced jack point with good result and that will take 2 wheels up. Others use the indicated jack point which is usually marked by a diamond shape just inboard to the rear of the aft wheel. This point is on a frame member and works well when I need to jack it up also taking 2 wheels up.
Easy to do just make sure you are doing it safely. Good luck and see ya on the road sometime.
