Anybody looking to mount snow tires on the IS300 for the winter months? I've been researching it a bit and found out a couple things: 1) There aren't many choices, especially if you want them mounted on the 17 inch rims, 2) They will need to be special ordered regardless of the brand. Lexus of Madison recommends Bridgestone Blizak but they want $844 for 4. I think I'm going with Michelin Alpines for about $610 for 4. Anybody else have any suggestions? Thanks..
