interior noise
I have recently purchased my first 04 c-5 coupe. The car has the GY run flats on it that are old and show cracks in the rubber. I am in the process of putting wheels and tires on it. However the car seems to have a lot of road noise. Maybe it's the tires (we shall soon find out). Years ago I was in the stereo business and we used a product call dyna mat to deaden sound. One day I read a report and that Car Stereo Review did and showed that the dyna matt did not help interior noise. Are there new products out now that are better? Do they really work? Do you experienced vette guys think my tires are just noisy? Maybe this is just a noisy car...My 82 c-3 didn't seem to be as loud as this one.

I agree. Getting rid of my old run-flats didn't do much for ride but sure quieted the road hum. You might also share what kind of exhaust system you have. Many owners feel loud pipes make C5's more enjoyable for some reason. That may also be contributing to your problem.

My car is completely stock. I can't even hear any exhaust probably because of the roar from these tires. I am gonna be dissapointed if the new tires don't reduce it a lot. any suggestion on a tire with minimul road noise? I am not racing or doing any competitive driving just cruising around.

I have an 02 ZO6. The road noise and heat from the underside was very noticeable. I installed some FROST KING heat duct insulation and it made a very noticeable improvement in both problem areas. Its thin, easy to install and once the carpet is back in, invisible!
I got mine at Home Depot. They also sell some foil covered bubble wrap which really helped with the tunnel heat.
Its an easy install that can be reversible if necessary:
If you think a C5 is noisy and hot,,, drive a C3 during a 90 deg summer day!
It made a big difference in the 71 Coupe also!
Compare the two sides. Covered and uncovered.
