If you want ride quality do not get run flats, they have stiffer sidewalls, great for cornering but bad for ride. I am happy with the gmax's I run on the back they have soft sidewalls. But for front I like stiff sidewalls to handle better. I do lots of interstate driving and the V groove tread on the gmax's do great in rain. Some reviews ppl say they can hear them but I do not notice any road noise. I have cat deleted though.
