Just curious, trying to figure out the problem (as a metallurgist). Were the tires ever removed from the wheel in question? Is this the first time rubber was in contact with the chrome? If a tire has come off from the chrome rim, did it take some chrome with it (from off the wheel) ?? If so, the chrome is peeling off from the wheel because it is stuck to the rubber and starting the leak.? Aluminum and chrome have very different thermal expansion coefficients and the chrome is much stiffer than the aluminum.
Just a thought. I don't actually know if this is the reason for the problem.

My guess would be chrome is tough to bond to using the adhesive they typically use for tires, and you are getting leaks between the chrome lip and the tire.
