Prior to installing these on my front-wheel drive Subaru wagon, I was driving on somewhat Goodyear Integrity all-season tires, and I had a hard time negotiating deep snow, slush and hardpack. Wet roads made driving on the Integrities a white-knuckle experience.
I switched to the Winterforce tires (set of 4) at the beginning of a winter when we received nearly 4 feet of snow in December alone. The tires produced a remarkable increase in snow traction, taking me where previously I would have only attempted to drive with my 4wd SUV. I live on a steep hill and I was surprised how well these tires worked climbing hills. I left them on year round which has reduced the tread life. I just ordered a new front set because after 32K miles about 1/8 of tread remains, and having just driven after a 13 snowfall, I am noticing a definite reduction in traction. I agree with others' comments about noise, but to me that noise is a song, my tires singing Let It Snow! I'll probably never go back to using an all-season tire. I plan to switch summer and dedicated winter tires from now on. These really got the job done in Wisconsin's winters.
