I also own a brand new GS450H that I love by the way but I'm a bit concerned about winter driving. I live in Montreal where winter can be very nasty. So as a 1st winter with a RWD vehicle, I'm wondering which brand of winter tires should I buy? Also, will I see a big driving difference if I pay for very expensive winter tires or low cost would do about the same? Thanks for your help. Pat
