Well the Goodyears that come with this car are basically crap. My wife made about 25k on them but do to my neglect in checking them as I did not even imagine I would have to this early, I think we should have replaced closer to 20k. Anyways, we just got a set of Yokohama YK520. From the reviews I read people got ~50k out of them and still looking good. No more shaking, much quieter and smoother ride. Feels a lot more controlled as well. So far so good. Yes, they are about $40 more per tire comparing to the Goodyears but its money well spend.
