The tires shouldnt come unglued. You didnt do a good enough job gluing. Clean up the wheels and tires and make sure you're using ca made for rc and do it again. Make sure you get glue all along the bead. Then put a rubber band around the tire. One on each side to hold pressure on it and let it sit. You can use a hair dryer to warm up the area a bit to make it dry faster. They should not come unglued.
