I've had the V12's for 10,000 miles and they are great. Someone in this thread said they won't grip as well as the stockers but they are wrong. The V12's out perform the stockers in every aspect. They have much more straight line grip when accelerating which is most important to the average driver. You get on it, you don't want to spin. They are very quiet and the ride is great. They do have more sidewall flex but the tire does not break loose. I have not had them break loose yet. I run 35 psi in the front and 40 in the rear which has helped reduced said flex. This is the tire most are getting after the stocker wear out.
