I'm going to get it tomorrow. We'll be doing a road test. I hear you about the 50 and up with tires. From 60mph to 120 this car is smooth as glass, and that was the same with 3 different sets of tires. Even at 55 when the noise is worst, you can't feel it in the steering wheel. It can't be heard/felt in the back seat, only the driver can hear it.
