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.
Now I'm a little worried as mine is a 2003 PT Cruiser My first thoughts if it happens to me would be to give one of those liquid tyre sealants a try. See below for an example or something similar.
Apparently certain wheels for certain year Chryslers are bad for this problem. It used to be discussed frequently on the 300M Club forums - not much any more because I think they beat the topic to death. My guess is it's been discussed on PT and other forums as well.
Here are some ideas that I got from reading those discussions: Some people use Fix-a-Flat. Some possible/claimed downsides of that are: It can be a mess for a tire shop to deal with later, it can cause imbalance (some people said that isn't true, others said it is true), it will mess up tire pressure sensors (not sure if that is true either) if you have those.
You can use RTV sealer on the bead when re-mounting the tires (after sanding or thoroughly wire-brushing) - that seems to be the favored way because you would have none of the claimed issues that you would have with fix-a-flat.
As future preventative, you could only inflate with dry nitrogen, or known-dry compressed air.

The following solved the chronic flat spare tire for one of my cars Years later, it is still at the pressure I left it at: Remove the tires from the rims, glass-bead (aluminum or steel rims) or sandblast (steel rims only) the rims in the area where the tires seat on the rims. Prime and paint the seat areas on the rims with gloss enamel paint. It doesn't matter what color -- clear will work as well as paint with pigment in it. Allow the paint to dry thoroughly. I applied several coats of paint. Warming the rims prior to painting speeds-up the drying time. Remount tires.

If you must use sandpaper, you should use the finest grit that will get the job done -- you don't want deep scratches into the rim. And if you must use RTV, you should use the non-corrosive variety (contains no acetic acid), such as Dow-Corning 4350, etc.
Otherwise, if you don't have a sandblaster, you can usually find someone to do it for you cheaply. Rattle-cans of enamel paint are dirt cheap too. This was the method recommended to me by a tire shop.
