If you're going to drive the G regardless of weather get the winter treads.

Got caught in a dusting, 1 -2 inches, last winter in my 6MT with summer tires. Was very lucky to make it home. I usually drive my 4X4 when there's a hint of winter weather and will be very conservative this winter.

 

LOL move here...we don't get any snow!

 

Even if there isn't snow on the ground you don't want to be on summer tires in the snow. I made that mistake and took my 6MT out when it was 20~ but bone dry and it was like driving on hockey pucks. The rubber is rock solid and has crap grip. If even a dusting hits the ground and you are out on the roads park it and call a friend, its not worth it. (I'm from Ohio so I'm not talking about Virginia snow). Everyone thinks they are a 'good snow driver' until you try to brake nice and easy coming to a stop sign and end up sliding into the middle of a 4 way intersection realizing you dodged a bullet.
