How are these hybrid vehicles in winter road driving conditions? I live in NE Ohio and drive 30 miles along the snowbelt highways. Infact our drive is uphill and a challenge to climb. Do any of you have experience with winter tires? I'm a believer in them, but wonder if I'll need studded snows for a hybrid based on it's balance (or unbalanced) characteristics. Going to test drive the Toyota and Honda varieties today! Thanks for any clues.
