Hey guys, I have an '08 IS250 with the X-Package. I'm pretty sure that comes with the Sports Suspensions and what not. I'm not all that knowledgeable when it comes to car parts so it might sound kinda stupid. Anyhow, for some reason, I think a Lexus should be a comfortable ride. The thing is, I think my car is just way too bumpy on the freeways and tires make way too much noise (bumpy noise). Is that because of the suspensions or the tires? Anyhow else having the same problem or feel the same way? Thanks.
