What a terrific forum this lexusownersclub is, I finally had to break down and join. My two cents on tires is this (at least for a 93 ls400) I had Pirellis on and when it came time to change, I researched the heck out of tirerack.com. I bought Yokohamas Avid V4s. They are V rated, relatively cheap (Discount Tire beat the tire rack price- about $400 out the door) but more more than that, they are QUIET at least so far they are- about 2500 miles. They are also rated as a very long wearing tire. Rather than take my word for it, I would go to the customer survey results at tirerack.com and compare them to other tires in the category. Also compare them to the Michelins. Comparatively speaking, I feel like I'm driving my living room.
