I dont believe there is a bolt thru the axle, but rather some type of threaded nut that is on the side of the axle this tire is on. I'm wondering if the entire axle has to be pulled in order to flip the rim. This fastner is not like a regular nut but rather it has a raised area that may need a special tool to remove. IT kind of looks like a top hat.
I thought of pulling the chain off and then moving the tire over the rim and replacing the tube, but I dont know if I will be able to position the tube correctly since the valve is now on the inside of the rim facing the blower. If I can do this then to inflate the tire I can raise the blower up and move the tire to a position whereby I can reach the valve stem and inflate the tire
