Tires usually get noisier as they wear, so I'd say the jury is still out on this one.
The Z51 Supercar tires on our 2009 weren't too noisy when new, but after 5k miles they were loud, and some of the grip had disappeared. The Michelins we now have on the C6 started out quieter than Goodyears and stayed that way.
It's not just a performance tire thing, we had some A/S tires I bought for a previous Toyota that got so loud I considered buying new/diferent ones even with over half the tread remaining.

Perhaps just another case of: "a little bit of knowledge is a dangerous thing."
But, I can't help but wonder if the "ackermann-caused" tire hop issue on C7 Corvettes is a predictable byproduct of Chevrolet's desire to provide the exceptional turn-in capabilities that many have raved about.
I am happy to be proven wrong about this, but, until then, I think that the "hopping" is just a price we pay to enjoy fabulous turn-in on the C7s.
I have a 2015 C7 Z51 coupe and I just LOVE the steering in general, but particularly the fabulous turn-in the car has. It's nothing like any car I have ever driven.

Exactly. And Chevy intentionally left out some sound deading to save weight. Some folks have added sound deading with pre-cut sound insulation and cargo mats, ordered the non-Z51 which has slightly taller sidewalls or replaced the run flats with standard A/S tires. I'm planning on all these when mine arrives. Nothing pleasant about road noise. This will cut down the noise without compromising performance of a DD.

I was incorrect, not knowing just what Chevy did to enhance turn-in.
But are you sure that Chevy used non-ackermann or do you really mean ANTI-Ackermann?
What is the source of your information that Chevy used non-Ackermann? I would like to read about it.
Thanks

I guess I'm one of the outliers because I think the tire/road noise in my Z51 convertible with the top up was pretty high on the drive from Bowling Green KY to Dallas, and will be putting in the sound deadening as soon as the weather straightens up here (we've had everything form of bad winter weather over the past couple of weeks - rain, snow, sleet, freezing rain), which is slowing me up on my projects.
The road noise is one of the negatives when comparing the Porsche Boxsters I've had to the C7.

Intended to look into installing insulation as some have, however found even with significant force, the rear carpeting wouldn't budge except that covering the battery. I have a '15 Coupe.

On many concrete highways, the tires sing and way too loud to hold a conversation.

I just added the dynamat extreme today, added the block-it kit, and put back my Lloyd cargo mat. The tire noise is less, but it's not a Mercedes quiet...
Of course, in sport mode, the exhaust adds sound!
