Winter wheels and tires made a huge difference in ride comfort.

Just installed the winter tires. Replaced the 235x50/18's with 215x60/17's. Of course you'd expect some change from the taller softer sidewalls. But the change was much more dramatic than I've noticed in other vehicles. The other thing I noticed was the winter tires and wheels (Michelin X-Ice and Elbrus i06) weighed much less than the stock Dunlops and premium wheels. I suspect, this difference in unsprung weight has as much to do with the difference as the softer sidewalls.

Thats a good point - lighter wheels will make a difference, so will softer and taller sidewalls.
