Classic Saab 9-5 (1997 - 2009)
I have the standard 17" Aero wheels on my 9-5 Airflow, currently the tyre size fitted on the wheel are 225-45-17. I wondered whether it would be possible to fit a 225-50-17 or 225-55-17, and whether this would make the ride any smoother/quieter?
Also, on previous cars I've liked to use Pirelli...
