One more question: I used to own a Legacy Outback wagon which had some issues with tires (even brand new ones) losing air slowly. Rims were wirebrushed, etc., but it was still an issue. Now that I have my grandfather's car (also a Legacy Outback wagon -- 1997), it is showing the same problem: slow loss of air in three of the tires.
Is there a known problem with rims in this model? If so, can anyone recommend the least expensive solution -- i.e., where to find inexpensive replacement wheels?
