Hi all, I have owned Mazdas for the last 15 yrs or so. Thinking about buying the CX, so went for a test drive a few days ago. I was concerned about the ride quality of the 20's so tried it out. Then after that, drove the one with 18 inch wheels over the same course. I really couldn't tell any difference in ride, but what I noticed right away was the higher level of tire/road noise with the 18 (yes eighteen) wheels. I was wondering if anyone else found this to be true. With Mazdas, its wonderful how the ride smooths out at highway cruising.
