My Michigan wheel loader has a tubeless tire that will go flat overnight. I put a soap solution all over the tire and inner and outer beads without finding a problem. When I put the soap on the metal rings of the wheel, a big cloud of bubbles quickly appeared. I am not equipped to take this big 20.5 x 25 tire off this 32K lb. machine, but would like advice first on how this wheel is constructed and if something just needs to be tightened, or welded, or what. Thank you.
