I had a log trailer years ago with tube tires and hated them. When I switched to tubeless type tires I had to change rim styles as well. I know I am comparing grapefruit and oranges, I also know that you can't run tubeless tires on tube rims and almost positive that tubeless rims with a tube are not compatible either but not 100% sure. Bad thing about tubes inside tires is the build up of extreme temperature if not properly inflated, more so if under inflated. Heat leads to blow out and that leads to trouble. Have spent as much money on lights, wires, air lines and hoods for someone else's car as I did on tires due to tube/tire failure. My point being this, a tire with dry rot is one of two things or both, being trouble or being dangerous. Best case is it is always flat when you need it. Worst is failure while traveling at highway speed. If one of tires was to fail a tube inside of it will be of no use because the tire will destroy it along with itself. A 38" tire would destroy your jeep before you could get it to stop, god willing you can maintain controll. Iwould stay away from them if I was you. Just passing on what I learned about the subject.
