These tires perform well when new. The problem is that after 30,000 miles the tread will be nearing replacement and noises/vibrations will grow increasingly worse. On my 2nd set after the dealership replaced the first set under warranty. Same problems with the first and second set. Alignment is fine. Wet and Snow traction is only good when the tires are relatively new as well.
I've had these on since November 2016 and drive roughly 100 miles round trip to work and back. I wish the rating system were more complex when rating winter tires on different road conditions because there are a handful of different types of weather conditions you will encounter in the winter. I will make an effort to rate these tires under different conditions you may experience. Along with my regular driving I make an attempt to do an unscientific in empty parking lots under different conditions.
Heavy Snow 4/5: There is no replacement for AWD/4WD, but these tires do well. Momentum is still key, but increased traction is noticeable.
Light Snow/Slush 5/5: Simply great.
Hard Packed Snow/Ice Mix 5/5: These tires really shine under these conditions.
Heavy Slush 2/5: Without the ability to get any grip from the road surface, these tires seem to struggle frequently in heavy slush during acceleration and turning.
Ice 2/5: While braking is slightly improved as well as turning at slow speeds, you cannot defy the laws of physics.
Warm Heavy Rain 2/5: The day that I installed these was after thanksgiving and we had an unusual 60 degree day with heavy rain. These tires perform poorly during breaking under these conditions.
I have mixed feelings about these tires and but when it comes down to it, they do perform better than all seasons in winter conditions. Ice and heavy slush will demand caution in any vehicle and these snow tires will not give you a big advantage in those conditions. Overall ride quality is great, handling is a little less precise but still very good. Cannot comment on tread life, but after 6,000 miles there is little to no noticeable wear. My fuel consumption has increased by 1-2mpg compared to previous winters.
I wish I could take back my old 5 year old tires and trade them for this brand. I also had an alignment done at the time of the installation of the new tires, so these sliding in wet conditions such as rain or snow is not due to the alignment; additionally I took my car in to the dealer because it's under warranty and they stated there's nothing wrong with the suspension, the issues with handling in wet conditions is due to the quality of the tires I chose
