I've only put a few hundred miles on these tires and I have to say they are light years better than the factory MXM4s. So far the tires are still pretty new so my review may not be accurate. This is mainly a first impression review. Very comfortable, quiet, and smooth. Not as harsh as the MXMs but you can tell performance wise they are a step down. Even though my driving style is considered spirited I was looking for more of a grand touring type of tire vs. a high performance. So far the MXV4s have been everything they were advertised to be. I'll be updating this review once I get more miles on the set.
