As a follow up, my mind is still in overload here, and I am thinking that it appears to be that I need to undo the 4 bolts holding the kit on, and slip the kit off, to replace either Trike tire.
This seems to be the most logical procedure, at the moment, while studying it again. Albeit, not practical if I'm on the go and away from home. Back to being Sherlock Holmes! LOL
