These tires have transformed the ride and wet weather performance of my Maxima. The original equiptment RSA's were replaced twice and wer never a good all around tire. The RSA's were great handlers, but frightenly inadequate in rain and snow. They were also rough and noisy. The P zero's however, are superb. The ride is very smooth, no whiring/droning sounds on the highway. When bumps are encountered there is no boom, slam or thuds, only distant thwacks and muted thuds. Wet performance is absolutely superb, I no longet have to drive 40 to 50mph on the highway to avaoid hydroplaning. These tires are not as aggressive as the RSA's but I have not lost ANY handling or feel. Just make sure with these you inflate to 37psi instead of the 32-33 reccommended by the manaufacturer. This will ensure you maintain the good steering feedback. These tires are just ok on ice and snow, but again this is not a four wheel drive vehicle. I would buyu these tires again without hesitation. Lastly, they balance up perfectly and there are no errant vibrations or chuggles to worry about.
