I have a 27 year-old daughter who is the owner of a 2005 Saab 9-3 Arc 2.0T sedan.
When it came time to replace her tires, good old dad (me) chose to send her Goodyear Eagle GT tires. Living in Indianapolis, she is at the southern edge of the snow belt. Rather than expect her to do a winter tire change over in the spring and fall she was a good candidate for all-season tires.
The tires being replaced were the Pirelli P6 Four Seasons tires. While not giving the performance of dedicated winter tires like the Bridgestone Blizzak WS60 or the Michelin X-Ice Xi2, this tire does give her the traction and performance for year-round driving. Two weeks after the Goodyears were installed she called to tell me replacing the tires was like buying her a new car. Noise levels were much improved as well.
