I'm on 19's with msport and in comfort mode it's like you're riding on 17's with high profile tires. Living on Long Island our roads are terrible and I was worried about bumps and such but it is very comfortable. In sport mode it stiffens up a bit and is still pretty good over bumpy roads. I would really like it to be a little stiffer but it still handles very well.
