Is there any?

With lower profile rubber you will find the 18's will tramline a bit more. Turn in may feel sharper as there is less flex in the reduced side walls, but if you push it to break-away it will be more sudden. The ride will probably be a bit harsher too, unless the 17's you're running are very stiff walled like RE070's for example.
