In Vermont, we run winter tires pretty much from November until April, so it's important to choose wisely when shopping for a new set. These Eagle Ultra Grip GW-3 winter tires replaced Michelin Primacy Alpin PA3 winter tires, and I couldn't be happier with the selection. Every objective measure of performance (and satisfaction) went up with the Goodyear tires: grip on icy surfaces; deep snow performance; slushy and wet road traction; and overall comfort (NVH). And on dry, cold roads, I really appreciate the stability and responsiveness of a performance winter tire -- especially in a heavy, V8 powered sedan. It's been a 'real' winter this year, and these tires have exceeded my expectations. Highly recommended.
