tires

Any new tire would be quieter until they start to cup, check yours and see if it has done that already. Plus the tire noise never goes completely away even with added insulation, but it all helps. Nothing will help tires that have already started to scallop/cup except replacement. One thing to note is the Super car tread allows you to rotate side to side which the EMTt & Super car EMT did not with non directional tread, it all helps.

You can do an all wheel alignment and stop the cupping from re-accruing when you put new tires on. Change the camber to as close to 0 as possible will negate the inner shoulder wear that is so prevalent. Toe, .05 left and right to also reduce scalloping of the tire edges. The tires should run longer and quieter, been there, done that.

Good luck and enjoy one of the best Corvettes ever built.

I can think of one method of de-cuupping perhaps... but you'll lose 1.4 of the tire meat. :)

Fun, but no good comes of hot trimming tires, not even machine turning them to true up the face. The heat set is already deeper in some spots and the cupping will come right back plus the noise remains.
