This is strictly a comfort tire, and does not strike a suitable balance between comfort and performance. The tires are extremely comfortable and quiet, providing a luxurious experience for passengers. For the driver, it is a different experience. If you are in touch with your car's performance, you will notice that they 'squish' or flex a lot during turns, numbing the response through the steering wheel. If you value steering feedback, this is not the tire for you.
These tires do fairly well in snow and rain, but still have a numb feeling that makes you second-guess when control matters most. I recommend Pirelli's P7 instead.
