I wanted to ask you how the ride quality is for these. I would love to have a spare set up 17inch for long road trips or long drives.
The ride quality is better with the 17" wheel and tire package compared to the 19" wheel and tire package that came with the car. I would imagine that the tire choice might make a difference too. The 17" tires that I went with prioritize winter/all season traction above comfort or fuel economy. A different choice might make the 17" ride even better.
I'm not sure that I personally would get a set of 17" wheels and tires just to put on during long road trips though. The 19" wheels/tires aren't bad on the highways in my neck of the woods. Most highways in my area have been repaved in the past few years- so the 19" wheels aren't horrible in terms of ride quality on the highway... just a bit noisy.
The main reason for the 17" wheels in my case is simply because I wanted a set that would handle the snow better in winter.
