Wheel Rim problems of the 2002 Chrysler 300M

I have a 2002 Chrysler 300m. The design of the wheel rim is bad. The rims of my car are badly corroded. It is not possible to see the corrosion due to the design of the wheel. My front tire, both, started losing air. This was noticed when I went to turned when it was raining and my car skidded. Luckily nobody was in the other lane. I took the car to get new tire and was told that it was not my tires it was the rim. The tire will not seal to the rim do to the corrosion. When I called the first representative hung up on me and was rude. The next person was very nice, but could not help me. I will replace the rims myself. I understand that rims sometimes do this, but as the tire place told me. Chryslers in particular this design on the 300m are by far the worst and they have never seen rims as corroded as mine.
