We had to drive our 2008 Prius last night (first experince with the Nokian's) through a blizzard in upstate NY Rt81 (Syracuse) area for over 100 miles and they performed FANTASTIC! There were at times... any where from an inch... to more than 3" + on the road way and the car never wavered a bit! I am a true believer in them now... and thanks to all those that had responded to my thread this past summer on which year round... "best tire" to put on was. Glad we went with the Nokian's !
