These tires replaced the original Bridgestone Potenza's (high performance, summer) that came with the G37. They are a noticeable step up in performance, primarily in the wet, compared to the Bridgestones. They are also quieter, though that may not be an accurate comparison as the Bridgestones were at the end of their life compared to the new Michelin's. This car does not get driven in the snow or ice so I have nothing to say in those regards. I recommend these tires to anyone looking for a tire with excellent all-round performance that is good in the wet.
