When a tire gets older it weakens and what possibly occurs is your weight combined with a turn cause the tire to come away from the rim slightly, then lose air pressure and while going forward it rolls the tire of the rim. The reason is a zero turn while turning exerts a sideways pressure on the rim/tire. Yor weigh adds to this side pressure. The only solutions are to air it to a higher pressure, fill with a compound to make it solid, or use a tube.
Below is one way to fill a tire with foam but you would need to research it thoroughly if you did this. Like for instance the amount of weight it would carry etc.
