Might anyone here have any thoughts regarding the use of snow tires on the 400? 18" wheels are not only extremely limiting toward a choice of tires, but generally a bit more rubber and less wheel is considered better for winter driving, as are narrower tires. I'm wondering how one might select the "proper" 16 - 17" wheel to stay within Lexus' guidelines? I'm unaware of a rating system for wheels as per measured torque, although one may well exist. Sorry for the duplication, as I originally posted in the wrong area in error.
