Living in Chicago, I'm getting ready to have to deal with this winter crap and needed some winter tires...Found some excellent winter tires called Bridgestone Blizzak LM-22. They're made in both 225/45/18 AND 245/45/18, so I can match factory exactly for both front and rear... They're not cheap ($200/ea)!! But I'd rather spend the dough, than slide into a curb and cause some serious, permanent damage to my G from trying to use the wrong tires in winter... Have heard about using 17", but that's a little too close for comfort over the Brembo's (1+ MM clearance?)... DonP, do you have Brembo's on your G??
