On the Ford Aerostar, I bought Dayton Quadra SE tires for it when the original's wore out at 55k miles years ago. The Quadra tires I believe are a 40-45k tire. Now those tires lasted on that van for over 70k miles! I was not very good at rotating them on a regular basis (only when I replaced the brakes or had some work done), but they still lasted a LONG time. I liked them so much that I put a second set on. They currently have over 40k on them, and will probably outlast the van! Another good thing about the Dayton's are the price: less than $200 for a set of 4. Since my Saturn will be due for new tires shortly, I just priced them for it (185/65R14) and they came in at $195 total. Just wanted to let anyone know if they're needing tires to possibly check them out.
