I'm currently running Bridgestone 255/30R19 square on the RS3 and contemplating a cross-country road trip from NC to CA which would be approx. a 6K mile round trip. Has anyone else gone this far on 30 series tires? If so, how was your overall experience with your low profile tires? I'll probably pass through Los Angeles and then up to Sacramento and I know there will be a lot of shitty roads along the way. I may end up taking my C63s with 35 series tires but it's on stock suspension and I'd feel less worried about bending a new rim on the trip. I'm leaning towards taking the RS3 because it's a blast to drive more so than the benz.
