You are not the only one to experience a rear rim crack, as currently my xfire is sitting on a rear driver side flat. As you tried to use the compressor and fix a flat with no success so have I. My tire is fine, but the rim has a inch long crack on the inside of the barrel. The tires are new and only have about 500 miles on them and I have not hit any pot holes or any other foreign matter in the street.
