I put these on in the middle of summer and they are really great looking tires. They handle the dry pavement here in Minnesota well. Our roads are not great and have some rough spots and these tires eat that up like nothing. I will have to give them a little lower grade for noise level but by no means more than average. The tires are great for wet weather traction and have deep channels to push water away from center of the tire.
As for fall and winter they made the transition great. They run just as well through deep snow better than average. They are not as good as snow tires but for those of us who don't want to swap tires twice a year they are perfect. They are great in cold weather (<0°F). They don't flat spot at all.
Tread wear looks good even with my spirited driving style.
To wrap it up I WILL be buying these again for a passenger car tire. They give me the looks I require from a tire and the performance I crave.
