I didn't notice a lot of change in traction or handling, which surprised me a little since I went from the 245 summer tires to 255 all-season tires. However, now that I have the car tuned I'm finding the limits of the all-season tires when it comes to traction off the line. My next set of tires will be summer tires since I now have a second/winter vehicle and I plan to stick with 255s when I do that. I definitely don't regret going with these 255 all-season tires, especially when we get a little snow...had the car out in about 3" of snow today and it handled great.
