The unfavorable evaluations make no sense to me; was it possible that you were sold a counterfeit? This is the fourth set of Pirelli tires that I've purchased, and while I haven't had any issues with them in the winter or summer, the ride quality is excellent. In the summer, after accumulating 45,000 kilometers (on a sedan), with a rear-wheel drive, I discarded the back pair of tires and saved the front tires for the next year. The tire has a good grip on the road, I didn't experience much yaw in comparison to bridgestone, and when accelerating from 0 to 50 miles per hour (with the gas pedal at full speed), the tire maintains superb control with no sign of slide or skid. Cons: It's a touch too soft, and you'll need to download a little bit more from the factory atmospheres specified.
