My 2003 PT Cruiser has slow air pressure leaks in both front tires. The tires have only 10,000 miles of wear. The service department has told me that the rims of the PT tend to corrode and the seals break and air does seep out (a design flaw). Other than removing the tires and sanding the rims periodically or buying better rims, is there any other way to resolve this problem? Thanks.
