How much do 19" wheels/tires improve comfort over 20" wheels?

[DaveT]

I noticed that Tesla sells 19" cyclones for the Model X, and I'm wondering how much comfort/smoothness in ride would they add over 20" wheels?

Please only reply if you own or have driven a Model X with 19" wheels. Thanks!

The 19" cyclones come with winter tires on them for areas where people switch between winter & summer tires. If you were to get them, you'd have to replace the winter tires with summer or all-seasons.

I purchased them for winter driving and they definitely feel more smooth and comfortable than my 20" Slipstream with the Performance Scorpion Pirelli tires. First thing I noticed when moving to summer tires how much more "softer" the 19" felt.
