I also live in So Calif, and there are a few roads that I have been on that create terrible tire noise. Mostly have been short sections of road, but it is defiantely loud when you are on the wrong kind of surface. I usually speed up to get off that section as soon as possible....
Doesn't happen often enough for me not to want the car, but certainly loud when it happens.

Not as noisy as my 1999 C5 Z51 or my 2009 C6 ZO6. Listened to music and audio books all the way back from Bowling Green without any problems. In Texas, had some very noisy I-10 road stretches, but it wasn't THAT bad.

Many concrete highways are grooved for water displacement. these tend to be noisy, as it's kind of like driving over rumble strips constantly. The noise increases particularly in cars with wider tires and lower to the ground. It is less noticable in 'normal' cars due to the narrow tire and suspension.

I do not think the c7 z51 is noisy except for the tire noise of course. The rear tires seem to be the worst offenders, on concrete. I am thinking of removing the rear inner fender wells and adding some sound matt material. Any thoughts on that are appreciated.

Man this car is noisy on the freeway, so much road noise. My car is a Z51 Coupe 3LT Auto.
At freeway speeds, one has to almost shout to hold a conversation with the person sitting next to you.
The stereo sounds great at slow/no speed, but speed up, and the road noise all but drowns it out unless you to crank it up to “give me a headache” volumes (and yes I do have the volume compensation thingy turned on).
This is not engine or wind noise, it appears to be coming from the tires.
And I can hear little stones hitting underneath the car quite a lot, it’s like there’s little or no sound deadening on this car.
I have no idea what the other generation cars interior noise level is like, since this is the first Vette I have ever owned.
I love the sport with a luxury touch ideal of the 3LT trim level, which is why I ordered it that way, but man that road noise is just spoiling it for me.
I installed a “partition” from Exoticvette as I had read in another thread that it helps with the road noise coming from the rear, and while it looks good and functions great as a partition, it did nothing to suppress any road/tire noise.
I suppose, since I think it’s mostly generated from the rock hard tiny super stiff sidewalled run flat tires, that my best option will be to hurry up and wear out the Michelins and look for a softer and quieter riding set of tires, and even maybe going up a smidge on the sidewall size, like from 35 to 40 for the fronts and from 30 to 35 on the rears, if they even come that size. Just thinking out loud here.
I really don’t feel like removing all the interior to install Dynomat to everything, but maybe I will have to if I’m to enjoy this car, which is my dream car, that I have been saving/planning for for the past 7 years.
Sorry for the long winded rant, I’m hoping to get some advise from others on this topic, maybe some advise on which tires brand/types would be best for me on this car.

I know the car is not nearly as loud when on asphalt, it's the grooved concrete hwys that make this car suck.

be careful when you make the switch away from run flats. I tried the same on my BMW 5 Series, and the ride became very squirrely. The suspension is calibrated based upon the stiffness of the side wall tires. Cars nowadays are so high tech, that any change can throw them for a loop.

To the OP
Although it has a lot of features found on luxury cars, it's a performance 'sports' car. It will out drive my Lexus in every category being a sports car. But my Lexus will feel more like a luxury car in every category and ride smoother and much quieter. Sound deadening adds lots of weight that would bring the performance numbers down. As the commercial said, every ounce had to earn it's way on board. Those wide rear tires are also going to add noise, especially on concrete highways. But they'll guide you where you want to go when lessor more quite tires will just do OK in that category.
