We test drove Expeditions with both the 20" and 18" chrome-clad wheels. It never crossed my mind that there was a ride difference until a salesman pointed out that the 20's had a firmer ride. Once I was clued in, there was definitely a difference felt. THe 20's were firmer but not the point of being harsh by any means. Noise level was NO different. On the upside, the 20's might corner slightly better, especially at higher speeds, but we're not talking sports handling here anyways.

In the end, I just thought the 18's looked nicer with their smooth face, rather than the indentions on the 20's.
