I live in Buffalo and I mounted these the week of Thanksgiving so I have a whole winter`s worth of driving to judge the quality of these tires.
Wet traction because I felt good road grip through puddles.
I did not experience any wheel spinning during accelerating and my PT cruiser felt secure during cornering. This happened during first lake effect event. It was a light snow event and this is why I gave the tires level 10 for light snow.
Driving down the highway during another snowfall, the PT felt very secure and I did not detect fishtailing or slipping. Also level 10 for highway driving
Good performance during very cold days, and I always felt in control of the PT.
During deep snow I had good grip accelerating but a little slippage cornering. That's why I only rated it level 8.
I found after very cold nights, snow packed in the treads does not melt and reduces the traction on the tires the next morning. I assume the same occurs on all snow tires.
I got temporarily stuck in a snow drift on an unplowed street during our first blizzard. I freed myself after a short time.
I give these tires a level 10 for getting out of the snowdrift.
Overall great product from General Tire.
