Wheel Rim problems of the 2001 Jeep Grand Cherokee

I had a slow leak in my rear tires , so I went to get them plugged. I was told that the rims had rusted through the back tires and punctured the tires. I could not get into a Jeep dealership for two weeks so my mechanic ordered a new rim (Jeep part) and two new tires so that I could drive safely. Jeep refuses to accept responsibility based on the fact that I had my own mechanic replace the tires. I was told that I should have waited two weeks. However, I was not going to risk driving on a faulty rim and tires. I still have the rusted out rims and punctured tires that Jeep refuses to acknowledge.

Contact took vehicle to a dealership to have yearly maintenance done. The dealership told him the tires were dry rotted. Also, the chrome rims were corroded. The plating inside the rims was corroded. He contacted the dealership, they told him they would replace two of the wheels, but he would have to replace the other two at his expense. Updated 12/27/05.

The car is only three years old with factory installed alloy wheel and after two years I noticed the chrome starting to chip off on all four rims. I recently replaced all four tires and was told that the rims were in even worse shape than I had expected. For the length of time that this occured and the extra money paid for the option, I just don't feel that this is right. I am over on my warranty miles and feel as if there is no recourse.
