If there's ANY kind of slush/snow on the ground, the G will be going nowhere. Trust me, I know...albeit I was running 285/30/20 or 275/35/19 summer tires those times. I picked up some snow tires for the G this year, and it did ok getting home when it snowed in the city, but couldn't even make it up a steep driveway. If you're on anything but dedicated snow tires, just borrow your bro's car to be safe. Oh, with how slammed my car is too, I'd bottom out for sure, and can't afford to slide into a curb. You'll be a little better off if you're at stock height.
