need to replace oem tires, any recommendations?

Hello, Your tire selection will depend on the type of driving you do, the climate in which you live, and preference for how you like your ride to feel. I would recommend visiting a local tire store (such as a Tire Rack or Discount Tire) and talking to them about your preferences. They will be able to make a better recommendation than someone who cannot see or know the car. If you'd rather research yourself, then here is a great link that will let you play around with different looks for your vehicle: http://www.tirerack.com/tires/SelectTireSize.jsp?autoMake=Volkswagen&autoModel=Passat+GL+TDI+Sedan&autoYear=2004&autoModClar= Best of luck!

If you're on a tight budget and for average driving (temporate climate), I've found that the Fuzion brand of tires is a good choice. Went up in size from the standard 195/15 to 205/15. They are moderately priced and wear, handle and ride very well. The down side is increased road noise.
