I'm considering replacing my Altima wheels this upcoming Spring with Mile Miglia Evo 5"s. Has anyone here that has upgraded to 18's on their SE felt a noticeable degradation in ride quality? The price difference for a set with Michelin Pilots is only about $300 so I would not be out a whole lot more if I decided to upsize. I'm currently running 35 lbs. of air on my current tires so, ride quality is already choppy. I guess one more thing to consider is that I normally don't race my car or drive over 70 MPH.
