Looks like the wheel hit a pothole and was bent. Doesn't leak at the bead but through the aluminum itself. Video: https://youtu.be/8fRZnWIrTnU Can this be fixed by coating the inside near the leak with a rubber coating?
I looked up Wheels America because that is where I got my smart wheel repaired at. Seems like the closest one to DC is in Lansdowne, PA. Google says about 130 miles. I was very happy with their Los Angeles (Buena Park) workmanship.
I wouldn’t repair. Structure has failed . Used is a good option . I have pothole anxiety every time I take out the Smarts this time of the year . Here in PA , the road crews haven’t gotten into rural road fixing just yet .
I have two front original smart wheels with tires mounted in perfect condition as I swapped them for two rears to mount on the front. They have about 3K miles on them. Been stored in an air conditioned room. I will sell both for $150, you pay shipping.
