We're picking up a CPO MAZDA6 Grand Touring at the end of the month to replace the Passat TDI (that I traded my MS3 for a few years ago) that we are returning to Volkswagen. I have a set of barely used 16" snows that are currently on the Passat that I'd like to repurpose on the 6. I see Tire Rack offers a 16" package for the 6, but after looking at a couple online Mazda parts providers, I'm assuming the 16" wheel used for this application comes from something else, like a 3. What should I be crossreferencing from/to?
