The grandson of a coworker just bought a Saab car. One of the wheels leaked air. When you look at the rim you can see the story of what happened to the rim and why it leaked.
Looking at picture 1 you can see a lot of dents on the bead that would be on the side of the rim on the inside of the car. (The non-spoke side) The other rim was fine. What happened was the previous owner had a flat and then continued to drive on gravel. Most likely the tire protruded on the spoke side, which protected it.
Looking at picture 2 you can see a crack in the rim that was filled with epoxy, most likely JB Weld. What happened is that the car hit a rock or pot hole which created a flat spot on the rim and cracked it. Picture 3 & 4 shows the crack from the tire side and the non-tire side after I removed the epoxy. Picture 5 shows the flat spot on the rim.
