Initial experience - this tire is so much better than the OEM Kuhmo Solus KH16, it's an unfair fight. Given my purchase of the P7 was for less than the Kuhmo here - slam dunk, game over.
The Solus was noisy, poor ride, so-so tread life and awful in snow. With the snowy winter we have had around SE Michigan this season, the improved performance of the Pirelli has been pretty astounding.
Although more miles are needed for a full assessment, thus far the snow, slush and dry performance of the tire has been excellent for a four-season tire. The ride and noise improvements are just as noteworthy. Highly recommended so far.
