Wheel Rim problems of the 2002 Chrysler Concorde

Aluminum rim tires on 2002 Chrysler Concorde develop leaks along seal with tire bead. Leads to slow leak and resulting low pressure tire. I was told by goodyear service center that this is common problem with these Chrysler aluminum wheels. To extent that someone does not notice tire loss of pressure, driving with severely underinflated tire could result in catastrophic tire failure. I have taken tire in for service - (remove tire and clean rim) but it is still leaking. I view this as a manufacturing or design defect, the rim should not fail to hold pressure.
