Yeah I've got the pirelli all seasons now, but dealer is swapping out for the pirelli ultra high Summers, as they were supposed to come on car. I do agree I notice tire noise as well, but the noise I'm hearing is drivetrain. I know the difference.Lots of good information and as most said, not much to do about it. Both of my SRTs had the same noise at around 50-60, depending on throttle input. Sometimes louder when coasting down a hill, sometimes when on the gas. With windows down, don't hear anything. Only when they are up do I hear it, but doesn't bother me. I've had worse rear whines, just about every V8 RWD car I've ever owned whined to some degree.
One thing to note, the stock Pirelli tires will start to whine/make noise after 10,000 miles. They'll just get worse and you'll swear its the rear diff. Its the tires. Big difference in sound once I replaced the stock tires.
