Hit the lock ring a few good ones to knock the rust off. Knock the bead down with either a tire hammer or bead breaker. Some people use wedges, but I can't seem to hit them. After a hit or 2 apply a generous amount of rubber lubricant such as RuGlyde. Allow it to soak a few minutes and knock the bead down so you can remove the lock ring. Then turn it over and give it a hit or 2 and put in a generous amount of RuGlyde and let it soak for a while. Then knock the bead down. Lay a block or something under the rim to elevate it about a foot or so. Then knock the tire off the rim with a hammer. When you have it about halfway down, push the stem in so it doesn't get stuck or smashed. If it doesn't want to go, give it some more RuGlyde. When you have the tire off, put a little air in the tube. This will help free the tube from the tire and the flap or snake belly. To mount the tire, put some tire talc in the tire to keep the tube from sticking. Put the tube in and inflate it a little. Then put the flap in and make sure that the tube has no folds and the flap doesn't pinch it. Stand the tire up with the stem down. Stick the stem through the hole and let the tire drop on the rim. It should slip on easily. Reinstall the lock ring or rings depending on if its one or 2 piece. Tap it a few times to make sure it is seated properly. Use a snap on inflater check, preferably one with a regulator set at the desired pressure. In being around them for over 50 years, I have never seen a lock ring blow off. But don't take any chances while you are inflating it. I used to change them in a matter of minutes 50 years ago. Now it tires me thinking about it.
