Ride comfort has several factors. For example, going from a 22” tire to a 20” tire will offer significantly more comfort. On the other hand, going from an 18” tire to a 20” tire may cause slight discomfort. Additionally, the width and aspect ratio of the tire also play a role in ride comfort. A lower profile sidewall will be much less comfortable than one that is larger. The same logic can be applied to the width of the tire.
