Not sure if you're referring to the OEM Supercar 3s that come on the ZL1, but mine do not have road noise and they grip just fine when the temps are in the optimal range for that tire
...I have no problem with the SC3'S and will most definitely buy them again when the time comes to replace them. I don't daily mine and dont drive it in cold temps or damp/wet conditions. Those that do definitely probably want something more "all season" for sure, which I can understand, but for me and how/when I drive, it'll be Supercar 3s all the time(as long as they make them)..
